11-Month-Old Milestones: Development, Growth, Speech, and Sleep

One month from a first birthday. Your baby pulls up on the coffee table, sidesteps along the couch, and lets go for a second or two before dropping to their bottom with a look of total surprise. The rest of the day is spent picking up tiny crumbs, dropping spoons off the high chair to watch them fall, and shadowing you from room to room.

Eleven months sits in the gap between the 9-month checkup and the big 12-month visit, so there's no dedicated CDC checklist for this exact age. What we can do is describe what most babies are doing between those two checkpoints, grouped the way your pediatrician thinks about it, with the numbers and the sources behind them.

Milestones at a glance

Most 11-month-olds are cruising along furniture, standing alone for a few seconds, using a neat thumb-and-finger pincer grasp, saying or approaching their first word with meaning, and getting clingy when you leave the room. The CDC's next formal checklist is the 1-year list, and each skill on it is something about 75% of babies can do by that age, not the average.¹² That framing matters at 11 months: your baby is working toward those items right now, and a wide spread in timing is completely normal.

Four rough tracks are maturing at once. Here's each one.

What should an 11-month-old be doing?

Movement and physical development

Cruising with confidence. By now most babies move along furniture with a sideways shuffle, one hand over the other, and they do it without much thought.³ Cruising is the direct rehearsal for walking, so the more couch laps, the better.

Standing alone. Many 11-month-olds let go and balance on their own for a few seconds before sitting down.³ Some stoop to pick up a toy from standing and push back up without holding anything, which takes real core and leg strength.

Maybe a first step. A first independent step can happen this month, but plenty of babies wait until well after their birthday, and that's expected. The WHO tracked when healthy children around the world hit walking, and independent walking has a window that stretches from about 8 to 18 months.⁴ An 11-month-old who only cruises is nowhere near late.

Now that your baby is upright and mobile, lower the crib mattress to its bottom setting if you haven't, and keep the floor clear of anything small enough to swallow. Everything still ends up in the mouth.

Hands and fine motor skills

A precise pincer grasp. Your baby picks up a single pea or a piece of cereal between the tip of the thumb and the tip of the index finger.³ This is the fine-motor skill that makes real self-feeding possible.

Dropping and releasing on purpose. At 11 months, letting go turns into a game. Food off the tray, spoon over the edge, again and again. It looks like defiance. It's actually your baby studying cause and effect and gravity.

Container play. Putting objects into a container and dumping them back out is an emerging skill right now, and it's on the CDC's 1-year list.¹ A bin of blocks and an empty cup can hold their attention for a surprisingly long stretch.

Speech and language

A first word with meaning. Around now, the babble starts to carry intent. "Mama" or "dada" gets aimed at the right parent, or a consistent sound reliably means a specific thing.¹ Some babies have a clear word at 11 months, others closer to 13 or 14 months, and both are normal.

Understanding more than they say. Your baby follows simple requests, pauses or briefly stops at "no," and looks toward a named person or object.¹ Comprehension runs well ahead of speech at this age, so a baby with no clear words yet can still understand a lot.

Jabbering in "sentences." Long strings of babble with the rise and fall of real conversation are typical now. It sounds like your baby is telling you a story in a language you almost recognize.

Waving and pointing. Waving bye-bye and pointing at what they want are early communication, and pointing in particular is a strong sign that language is coming along.¹

Social and emotional

Separation anxiety. Clinginess when you leave the room is at its loudest right now. It builds through the second half of the first year, and by the 9-month checkpoint most babies already react when a parent walks away, by looking, reaching, or crying.⁵ At 11 months it can feel relentless. It means your baby has a secure attachment to you, not that anything is wrong.

Strong preferences. This is the age of opinions. A favorite cup, a specific blanket, the food they loved yesterday and reject today. Your baby is figuring out that their choices produce results.

Copying you. Babies this age imitate constantly, from waving to "talking" on a toy phone to trying to brush their own hair. Playing peekaboo and simple back-and-forth games is a favorite, and it's the social groundwork the 1-year checklist builds on.¹

How much sleep does an 11-month-old need?

About 13 hours in 24, typically around 10.5 at night and 2.5 across 2 naps.⁶ Wake windows are the longest they've been, near 3 to 4 hours, with the last window before bed a bit shorter than midday.

Eleven months is still firmly a two-nap age, and the drop to one nap usually waits until 14 to 15 months. If your baby is fighting the morning nap, that's normal and rarely a sign it's time to drop it. We break the whole day down, with a sample schedule and the approaching 12-month regression, in our 11-month-old sleep schedule post, and the numbers for every age live in our wake windows chart.

Feeding an 11-month-old: table foods, self-feeding, and the open cup

At 11 months your baby is mostly eating soft versions of what the family eats, in small pieces, and feeding themselves with their fingers.⁷ Most are on three meals plus a snack or two, alongside breast milk or formula. The pincer grasp is what makes finger foods click at this age.

Keep the common allergens in the rotation rather than avoiding them. The LEAP trial found that regularly feeding peanut to high-risk infants from 4 to 11 months cut their chance of peanut allergy by roughly 80% by age 5.⁸ National guidelines now recommend introducing peanut, egg, and other allergens early and keeping them in the diet in age-appropriate forms.⁹ If your baby has severe eczema or a known food allergy, check with your pediatrician on the approach.

An open cup is worth practicing now, even though it's messy. Offer water with meals, and keep it to no more than about 1 cup (8 ounces) a day for 6- to 12-month-olds, since milk still covers most of their fluid needs.¹⁰ Whole cow's milk as a drink and honey both wait until the first birthday.

A quick word on teeth. By 11 months many babies have four to eight teeth, usually the incisors on top and bottom, but the range is wide and a baby with only one or two (or none) is still normal.¹¹ Our feeding guide has amounts and frequencies broken out by age.

Growth at 11 months

Weight gain has slowed a lot since the newborn months. This month most babies add somewhere around three quarters of a pound to a pound and grow close to half an inch.¹² A little more or less either way is normal, especially for a baby who is now burning calories cruising all day.

Your pediatrician plots height, weight, and head circumference against the WHO growth standards at well visits.¹³ The curve is what matters, not a single number. A baby who has tracked the 25th percentile since birth and keeps tracking it is growing exactly as they should.

11-month milestone checklist

Development is a range, not a schedule, and no baby hits every item on the same week. Most 11-month-olds can:

• Cruise along furniture with confidence
• Stand alone for a few seconds
• Pull to stand and stoop back down
• Use a neat thumb-and-finger pincer grasp
• Put objects into a container and take them out
• Drop and release things on purpose
• Say or approach a first word with meaning
• Follow a simple request and respond to "no"
• Wave bye-bye and point at what they want
• Show separation anxiety when you leave

11-month red flags: when to call the doctor

Every baby is on their own timeline, but a few signs around this age are worth raising with your pediatrician. Check in if your baby¹:

• Isn't crawling or has trouble bearing weight on their legs when held
• Doesn't search for a toy they see you hide
• Doesn't babble strings of sounds like "mamama" or "bababa"
• Doesn't point at things or use gestures like waving
• Doesn't respond to their own name
• Seems unusually stiff or unusually floppy
• Loses skills they previously had

None of these on its own means something is wrong, and you know your baby better than a list does. If something feels off, the "act early" move is to ask sooner rather than wait and see.²

How to support development at 11 months

Make cruising and standing worth it. Set a favorite toy on the couch so your baby has to pull up and sidestep to reach it. That builds the balance and leg strength behind walking. Barefoot on non-slip floors gives the best grip.

Narrate and offer choices. Name what your baby points at, and give small real choices ("the red cup or the blue cup?"). Both feed the language that's about to take off and respect the strong preferences showing up now.

Practice sitting down from standing. A lot of nighttime crying at this age is a baby who stood up in the crib and can't figure out how to get back down. Hold their hands during the day and guide them from standing to sitting so the skill is automatic by bedtime.

Keep allergens in the rotation. Small, regular amounts of peanut, egg, and dairy in age-appropriate forms are what the research links to lower allergy risk.⁸ Consistency matters more than quantity.

nappi keeps feeds, sleep, and milestones in one place, so the 1-year well visit becomes a matter of glancing at what actually happened instead of reconstructing it from memory.

Frequently Asked Questions

Is it normal that my 11-month-old isn't walking yet?

Completely. Cruising along furniture is the typical skill at 11 months, and independent walking has a wide window that runs from about 8 to 18 months.⁴ A baby who cruises well and stands for a second or two is right on track, even with no steps yet.

My 11-month-old only babbles and has no real words. Should I worry?

Usually not. Comprehension leads speech at this age, so a baby who follows "come here," responds to their name, and points is communicating well even without clear words.¹ First words often land closer to 12 to 14 months. If your baby isn't babbling strings of sounds or using any gestures, mention it at the 1-year visit.

Why is my 11-month-old suddenly so clingy?

That's separation anxiety, and it's loudest in the second half of the first year. Reacting when you leave the room is expected by the 9-month checkpoint and often intensifies after.⁵ It's a sign of secure attachment. Brief, cheerful goodbyes and short practice separations during the day help.

How many teeth should an 11-month-old have?

Anywhere from none to about eight, most often the top and bottom front teeth.¹¹ The timing of teething varies enormously, and a late first tooth on its own isn't a concern.
