The CDC defines milestones as things most babies, 75 percent or more, can do by a certain age. There is no 11 month checklist. The one behind you is 9 months, when most babies get to a sitting position by themselves and sit without support. [3] The one ahead is the 1 year list, and at 11 months you are close enough that much of it may be showing up in your living room already. Treat it as a preview, not a test your baby must pass today. [1]
Standing is the theme of the month. The CDC lists pulling up to stand and walking while holding on to furniture among the milestones most babies reach by 1 year. [1] The AAP describes the usual sequence: your baby pulls to a standing position every chance they get, cruises sideways along the couch, and as balance improves, may let go for a moment before grabbing support again. [2] Those wobbly hands-free seconds are the direct rehearsal for walking. The AAP notes that most babies take their first steps around the first birthday, and starting earlier or later than that is normal. An 11 month old who is walking is normal. An 11 month old with no interest in standing yet has runway too. [2]
Two practical notes from the AAP for this stage. First, a baby who pulls up may not know how to get down: if yours cries for help, show them how to bend their knees and lower themselves instead of lifting them down each time. Second, check that anything your baby cruises along has no sharp edges and is properly weighted or attached to the floor so it cannot tip. [2] And if crawling is still the main gear, that is fine. The AAP describes crawling as a skill usually mastered between 7 and 10 months, styles vary from classic hands and knees to scooting, and what matters is that your baby coordinates both sides of the body and uses each arm and leg equally. [2]
Hands are getting precise. By the first birthday, the CDC list includes picking things up between thumb and pointer finger, like small bits of food, and putting something into a container, like a block in a cup. Watch your baby at mealtime and during play and you will see both in rehearsal. [1]
The mind is doing quiet, remarkable work too. Around this age babies grasp object permanence: the understanding that a thing still exists when it is out of sight. The AAP points to peekaboo as the classic workout for this idea, and the CDC lists looking for things they see you hide, like a toy under a blanket, as a milestone by 1 year. A baby who lifts the blanket to find the toy has just done real problem solving. [6] [1]
Words are close, and may already be here. The AAP counts as a first word any sound your baby uses consistently to refer to the same person, object or event, so "ba" for bottle counts. [4] By 1 year, most babies call a parent "mama" or "dada" or another special name, wave bye-bye, and understand "no", pausing briefly or stopping when you say it. Whether they choose to stop is a different question, and that part is normal too. [1]
Emotionally, clinginess is still the weather. Separation anxiety usually peaks between 10 and 18 months, so month 11 sits right in the thick of it. Your baby protests when you leave because they know exactly who you are and prefer you present. The AAP notes babies are more susceptible when tired, hungry or sick. It is attachment doing its job, and it fades. [5]
The CDC lists 12 to 16 hours of sleep per 24 hours for infants 4 to 12 months, naps included. Babies vary, so count the whole day rather than judging the night alone. [7]
Separation anxiety works nights as well as days. A baby who cries the moment you leave the room at bedtime is moving through a normal stage, not testing you. Short, warm, predictable goodnights are easier on everyone than long dramatic exits. [5]
Safe sleep rules hold until the first birthday and beyond. Use a firm, flat sleep surface and keep soft objects and loose bedding out of the sleep area, since pillows and blankets raise the risk of suffocation. [8] A confident stander will stand in the crib, sometimes at 2 a.m., and may cry there, stuck upright. Practicing the bend-the-knees, sit-back-down move during the day saves night trips. [2]

Open the week calculatorAn 11 month old eats on a nearly grown-up rhythm. WHO guidance for infants 9 to 23 months is 3 to 4 meals of solid foods per day, with 1 to 2 snacks as needed. [10]
Breast milk or formula is still the main drink, and both work. The AAP sample menu for 8 to 12 month olds is built around roughly 24 ounces (720 mL) of breast milk or formula a day, with solid food portions of about 2 to 4 ounces, in textures like mashed or diced fruit, diced cheese, and pureed or diced vegetables, beans or meat. Soft, small pieces your baby can pick up are exactly right: every diced pear cube is pincer grasp practice. [9] [1]
A change is coming at 12 months, not now. The AAP advises plain whole milk for children 12 to 24 months, so cow's milk as a main drink waits until after the first birthday. [11] Families who breastfeed do not need to switch at all if they prefer: WHO supports continuing breastfeeding up to 2 years of age or beyond. [10]
Water stays in the routine: about 4 to 8 ounces a day at this age, offered in a cup. The CDC 1 year list even includes drinking from a cup without a lid as you hold it, so every practice sip counts twice. [11] [1] Juice can wait. The AAP states that infants under 1 year should not drink juice at all, and that eating fruit is always preferred to drinking it. [11]
Most of what an 11 month old throws at you is ordinary. A short list of signs deserves a call, so you never have to wonder.
Fever. A fever above 104 F (40 C) repeatedly, at any age: call your child's doctor. A fever that lasts more than 24 hours in a child younger than 2 years: call, even if no other symptoms show. A fever along with a seizure, or a child who still acts sick once the fever comes down: call right away. [14]
Dehydration. Fewer than six wet diapers in a day, or a parched, dry mouth: the AAP lists these as signs of dehydration and advises notifying the pediatrician immediately. Fewer tears when crying and sunken eyes belong on the same list. [15]
Movement. Your baby uses one side of the body much more than the other, or does not use each arm and each leg equally: bring it up with your doctor. [2] An 11 month old who is not yet sitting without support is well past the age when most babies do, so that deserves a conversation too. [3]
Skills. Your baby has lost a skill they once had, or is missing several milestones as the first birthday approaches: share that with your doctor and ask about developmental screening. Acting early helps, and most of the time the answer is reassurance. [1]

The first birthday is a milestone month in every sense. By 1 year, the CDC list includes pulling up to stand, walking while holding on to furniture, drinking from a cup without a lid as you hold it, picking things up between thumb and pointer finger, waving bye-bye, calling a parent "mama" or "dada", looking for hidden things, and pausing at "no". Most of it is in rehearsal right now. [1]
First steps tend to cluster around the birthday itself, and the range on both sides is wide and normal. Once they come, the AAP notes most children go from shaky first steps to confident walking within days. [2]
The menu shifts at 12 months too: plain whole milk becomes the advised main milk for children 12 to 24 months, replacing formula, while breastfeeding families can simply continue as long as they like. [11] [10]
Yes. The AAP notes that most babies take their first steps around the first birthday, and it is normal for children to start walking earlier or later than that. The CDC milestone list for 1 year includes pulling up to stand and walking while holding on to furniture, not walking alone. An 11 month old who is cruising, or still mostly crawling, is on schedule. [2] [1]
The CDC lists 12 to 16 hours per 24 hours for infants 4 to 12 months, naps included. Babies vary, so count the whole day rather than the night alone. [7]
The AAP advises plain whole milk for children 12 to 24 months, so the switch to cow's milk as a main drink waits until after the first birthday. At 11 months, breast milk or formula still anchors the day: the AAP sample menu for 8 to 12 month olds is built around roughly 24 ounces (720 mL) a day. Families who breastfeed can simply continue: WHO supports breastfeeding up to 2 years of age or beyond. [11] [9] [10]
