Week 35 old
At week 35 (about 9 months), many babies are on the move, eating three solid meals plus milk, and settling into two predictable naps. Here's what's typical now.
In short
Around week 35, many babies eat three solid meals a day alongside 24-30 oz of breast milk or formula, sleep about 13-14 hours total with two naps, and are busy crawling, pulling up, or sitting steadily.
🍼 Feeding
About 24-30 oz of breast milk or formula per day, plus roughly three solid meals (a few tablespoons each, building toward 1/4-1/2 cup) with a variety of textures. Offer water in a cup with meals.
😴 Sleep
Around 13-14 hours total: about 10-12 hours overnight plus two naps. Wake windows are typically 2.5-3.5 hours. Always back to sleep on a firm, flat surface with no loose bedding, pillows, or bumpers.
What's happening this week
- •Around this age, many babies sit without support and may crawl, scoot, or pull up to stand at furniture.
- •Object permanence is developing, so many babies look for a toy you hide and may protest when you leave the room.
- •The pincer grasp is emerging — many babies start picking up small bits of food between thumb and finger.
- •Babbling often gets richer now, with repeated sounds like 'mama,' 'dada,' and 'baba' (not yet always with meaning).
- •Stranger and separation anxiety are common and normal around this stage.
Milestones to keep in mind
- ✓These are ranges, not deadlines: the CDC's 9-month checkpoint is the relevant guide, and babies reach each skill on their own timeline.
- ✓By the 9-month checkup, many babies sit without support and pass objects from one hand to the other.
- ✓Around now, many babies respond to their own name and look toward familiar people and things you name.
- ✓Many babies are babbling strings of sounds and showing different reactions to happy versus upset voices by the 9-month checkpoint.

💡 Tip for this week
Now that your baby can pull up and reach, do a quick floor-level safety sweep: secure furniture to walls, move cords and small objects out of reach, and lower the crib mattress if you haven't yet.
⚠️ When to call your pediatrician
Call your pediatrician if your baby isn't bearing any weight on their legs when held, isn't babbling or making sounds, doesn't respond to their name, has lost skills they once had, or shows fewer wet diapers, poor feeding, or a fever of 100.4°F (38°C) or higher.
Frequently asked
How much should a 9-month-old (around week 35) eat?
Most babies this age take about 24-30 oz of breast milk or formula across the day plus roughly three solid meals, with milk still the main source of nutrition. Amounts vary, so follow your baby's hunger and fullness cues.
How many naps does a baby take at 9 months?
Many babies this age have settled into two naps a day with wake windows of about 2.5-3.5 hours, totaling around 13-14 hours of sleep including overnight. Some are starting to resist one nap, which is normal.
Is it normal for my baby to suddenly cry when I leave the room?
Yes. Separation and stranger anxiety are very common around this age as object permanence develops. Brief, calm goodbyes and consistent routines usually help your baby learn that you always come back.
