Week 36 old
At week 36 (about 9 months), your baby is on the move, eating real meals, and forming strong attachments. Here's what's typical this week.
In short
At 36 weeks (around 9 months), many babies are crawling or cruising, eating three solid meals plus 24-30 oz of breastmilk or formula a day, and sleeping about 14 hours total with two naps.
🍼 Feeding
Around 24-30 oz of breastmilk or formula per day, plus three meals of solids and possibly a snack. Soft finger foods and a wide range of textures are great now; offer water in an open or straw cup with meals.
😴 Sleep
About 13-15 hours total, usually 11-12 hours overnight plus two naps. Wake windows stretch to roughly 2.5-3.5 hours. Keep the crib bare — back to sleep, firm flat mattress, no loose bedding, pillows, or bumpers.
What's happening this week
- •Around this age, many babies are crawling, scooting, or pulling up to stand and cruising along furniture.
- •Many babies now use a pincer grasp, picking up small bits of food between thumb and finger.
- •Separation and stranger anxiety often peak around now — clinginess and crying when you leave are normal signs of healthy attachment.
- •Babbling often takes on real speech rhythm, with strings like "mama" and "dada" and copying of sounds and gestures.
Milestones to keep in mind
- ✓This week falls near the 9-month checkup, where your pediatrician will screen development — these are ranges, not deadlines, so timing varies widely from baby to baby.
- ✓By the 9-month checkpoint, many babies sit without support, get into a sitting position on their own, and pass objects from hand to hand.
- ✓Many babies look for a dropped or hidden toy around now, an early sign of object permanence.
- ✓Many respond to their own name and react to your tone of voice by this age.

💡 Tip for this week
Now that your baby is pulling up, lower the crib mattress to its lowest setting and do a fresh baby-proofing sweep at floor level — secure furniture to the wall and move small choking hazards out of reach.
⚠️ When to call your pediatrician
Call your pediatrician if your baby isn't bearing any weight on their legs, doesn't babble or make sounds, doesn't respond to their name, has lost skills they once had, isn't sitting without support, 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 eat?
Around this age, most babies have about 24-30 oz of breastmilk or formula a day alongside three meals of solid food. Milk is still the main source of nutrition, with solids building skills and variety.
Why is my 9-month-old suddenly so clingy?
Separation and stranger anxiety often peak around 9 months. It's a normal, healthy sign of attachment — your baby now understands you can leave, and reassurance plus consistent goodbyes help.
Is it normal that my baby isn't crawling at 36 weeks?
Yes. Crawling timing varies a lot, and some babies skip it entirely, scooting or going straight to pulling up and cruising. Mention any concerns at the 9-month checkup, where your pediatrician screens development.
