Week 51 old
Week 51: your baby is days from turning one. Expect three solid meals, a shift toward one nap, and big personality. Here's what's normal.
In short
At 51 weeks (almost 12 months), most babies eat 3 meals plus 1-2 snacks alongside about 16-24 oz of breast milk or formula, sleep around 11-14 hours total, and are cruising, standing, or taking first steps — all within a wide normal range.
🍼 Feeding
3 meals plus 1-2 snacks of varied solids, alongside roughly 16-24 oz of breast milk or formula per day. Whole cow's milk in a cup is usually introduced at the 1-year mark — check with your pediatrician.
😴 Sleep
About 11-14 hours total per 24 hours, including 2-3 hours of daytime sleep. Many babies are transitioning from two naps to one around now, with wake windows of roughly 3-4 hours. Keep the crib bare and place baby on their back.
What's happening this week
- •Around this age, many babies pull to stand and cruise along furniture, and some take their first independent steps — though plenty of healthy babies don't walk until 15-18 months.
- •Many babies now use a neat pincer grasp to pick up tiny pieces of food and may try a spoon or cup.
- •Around the first birthday, lots of babies say one or two words with meaning, like 'mama,' 'dada,' or 'bye,' and understand simple requests.
- •Object permanence is strong now, so many babies look for hidden toys and may show stranger or separation wariness.
Milestones to keep in mind
- ✓By the 12-month checkup, the CDC looks for things like pulling to stand, getting to a sitting position, and using a pincer grasp — all framed as ranges, not deadlines.
- ✓Around 12 months, many babies wave bye-bye, bang two objects together, and look for things you hide.
- ✓By the 1-year visit, many babies copy gestures and respond to their own name; not yet doing all of these is common and worth simply mentioning to your pediatrician.
- ✓Walking is NOT a 12-month milestone — most babies who aren't walking yet at one year are completely on track.

💡 Tip for this week
Plan the 1-year well visit now — it usually includes a developmental check, hemoglobin and lead screening, and vaccines. Jot down any words, gestures, or feeding questions so you don't forget to ask.
⚠️ When to call your pediatrician
Call your pediatrician if your baby has lost skills they once had, isn't bearing any weight on their legs, makes no babbling or gestures, has fewer wet diapers, isn't gaining weight, or runs a fever — and trust your gut if something feels off.
Frequently asked
How much should an almost-1-year-old eat?
Most babies near 12 months eat 3 meals plus 1-2 snacks of soft, varied table foods, plus about 16-24 oz of breast milk or formula a day. Appetite often dips as growth slows, which is normal.
Is it normal that my baby isn't walking at almost one year?
Yes. Walking typically happens anywhere from about 9 to 18 months, and most one-year-olds who aren't walking yet are perfectly on track. Cruising, pulling to stand, or crawling are all good signs of progress.
When can my baby switch from formula to cow's milk?
Whole cow's milk in a cup is generally introduced at 12 months, not before. Confirm timing and amounts with your pediatrician, especially if your baby has allergies or feeding concerns.
