Week 45 old
Week 45 (around 11 months): what to expect with your baby's feeding, sleep, cruising, and the approaching 12-month checkup. Warm, range-based guidance for anxious parents.
In short
At 45 weeks (about 11 months), most babies are eating three meals plus snacks alongside breast milk or formula, sleeping roughly 13-14 hours a day across two naps, and busy cruising along furniture. Development is best measured as a range heading toward the 12-month checkup, not week by week.
🍼 Feeding
Typically about 16-24 oz (roughly 480-720 ml) of breast milk or formula a day, usually across 3-4 nursing sessions or bottles, plus three solid meals and one or two snacks. Solids are now the main source of nutrition for many babies this age. Offer water in an open or straw cup with meals. Whole cow's milk and honey are still best held until 12 months.
😴 Sleep
Most 11-month-olds sleep about 13-14 hours total: roughly 11-12 hours overnight plus two naps totaling 2-3 hours. Wake windows are commonly around 3-4 hours, stretching toward the end of the day. Some babies start hinting at dropping to one nap, but most still need two; an early bedtime helps on short-nap days.
What's happening this week
- •Around this age many babies are cruising confidently along furniture and may stand alone for a few seconds, though the range for these skills is wide and totally normal
- •Pincer grasp is often refined now, so many 11-month-olds pick up small bits of food neatly between thumb and forefinger
- •Babbling around now frequently includes 'mama' and 'dada' with meaning, and some babies use one or two other simple words
- •Many babies this age understand short, familiar requests like 'wave bye-bye' or 'give me the ball,' and separation anxiety is commonly at a peak
Milestones to keep in mind
- ✓By the upcoming 12-month checkpoint, many babies pull to stand and cruise; standing alone and first steps vary widely and may come weeks before or after the first birthday
- ✓By around 12 months many babies use simple gestures like waving or pointing, and may say one or two words besides mama/dada
- ✓Around this age many babies look for hidden objects and copy gestures or sounds you make
- ✓By the 9-to-12-month range many babies feed themselves finger foods and may help while being dressed; remember these are ranges, not deadlines

💡 Tip for this week
As your baby cruises and pulls up more, do a quick floor-level safety sweep: anchor tall furniture and TVs to the wall, move anything heavy or tippable out of reach, and pad sharp coffee-table corners. Falls and furniture tip-overs are among the most common injuries at this active, upright stage.
⚠️ When to call your pediatrician
Call your pediatrician if your baby has fewer than 4-6 wet diapers a day, signs of dehydration, refuses to bear any weight on their legs, has lost previously mastered skills, isn't babbling or responding to their name, makes no eye contact, or seems unusually floppy or stiff. For any baby, a fever of 100.4 F (38 C) or higher, breathing trouble, persistent vomiting, or a baby who is very hard to wake or unusually listless warrants a prompt call. Trust your instincts and reach out whenever something feels off.
Frequently asked
How much should my 11-month-old be eating?
Most babies this age have three meals plus one or two snacks alongside about 16-24 oz of breast milk or formula a day. Solids are becoming the main source of nutrition, and appetite can swing day to day, which is normal. Keep offering a variety of soft, safe finger foods and let your baby decide how much to eat.
Is it normal that my baby isn't walking yet at 45 weeks?
Yes. Walking has a wide normal range, and many babies don't take independent steps until well after their first birthday. At this age, cruising along furniture and pulling to stand are common and reassuring signs. If your baby isn't bearing weight on their legs at all or has lost skills they previously had, mention it to your pediatrician.
Should my baby still take two naps at 11 months?
Most 11-month-olds still need two naps, totaling about 2-3 hours, even though some begin showing early signs of moving toward one nap. There's no rush to drop a nap. If naps get short, an earlier bedtime usually helps protect overall sleep until your baby is truly ready for the transition, which often happens closer to 14-18 months.
