12-Month-Old Baby

Happy birthday baby! You’ve now got a 1-year-old on your hands! Baby’s been on an amazing journey in her first year, hasn’t she? And so have you, watching her advance from rolling to cruising -- maybe even walking unsupported. (If she’s not there yet, don’t worry. Many toddlers start walking after their first birthday.) She’s probably pretty social now, waving “hi” and “bye” and likely using most 1-year-olds’ favorite word, “no,” while shaking her head. Make way for toddlerhood!

your baby is 1 year old!
  • She still likely sleeps about 13 hours per day with two naps.
  • She has 3 meals and 1 to 3 snacks per day. Baby can probably feed herself by now.
  • She’s probably still growing about a half inch each month and gaining 3 to 5 ounces per week. But look out: Many babies go through a growth spurt right around 12 months.
  • She likely stands for a few moments without support, and may walk 2 or 3 steps.
  • She is probably saying "dada", "mama" and at least one other word. (And yes, if you understand what she means, it counts as a word!) She also understands one-step commands if you use gestures.
  • To help baby’s language development, read to her every day. If you speak a second language, use it around baby.
