Week 43 old
Week 43 of your baby's first year: a busy 10-month-old who's cruising, babbling, and eating more like the family. Here's what's typical.
In short
At 43 weeks (about 10 months), many babies are crawling well and pulling up or cruising along furniture, eating three meals plus a couple of snacks alongside about 24 oz of breast milk or formula a day.
🍼 Feeding
Around 24 oz (about 720 ml) of breast milk or formula a day, plus three meals and one to two snacks of soft, varied solids. Offer water in an open or straw cup with meals; cow's milk usually waits until 12 months.
😴 Sleep
Roughly 12-15 hours total, usually 2 naps a day with wake windows of about 3-4 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 pull to stand and cruise sideways while holding furniture, though some aren't there yet and that's still within the normal range.
- •Many 10-month-olds use a neat pincer grasp, picking up small bits of food between thumb and forefinger.
- •Babbling around now often sounds like real conversation, with strings like 'mama' and 'dada' and copying of your tones.
- •Object permanence is strengthening, so peekaboo and looking for a hidden toy are big hits.
Milestones to keep in mind
- ✓Milestones cluster around the 9-month checkup and the next one at 12 months rather than any single week. By the 9-month visit, many babies sit without support, transfer objects hand to hand, and respond to their own name.
- ✓Looking ahead to the 12-month checkup, many babies are pulling to stand and may take steps holding on. Walking ranges widely, from about 9 to 15 months.
- ✓Most babies this age look for things they see you hide and use simple gestures like reaching to be picked up.
- ✓Every baby's timeline differs. If your baby isn't doing some of these yet, mention it at the next visit rather than worrying alone.

💡 Tip for this week
Now that pulling up is common, do a quick floor-level safety sweep: anchor furniture and TVs to the wall, move cords and small objects out of reach, and lower the crib mattress if you haven't already.
⚠️ When to call your pediatrician
Call your pediatrician for fewer wet diapers than usual or signs of dehydration, a fever of 100.4°F (38°C) or higher, refusing to eat or drink, no weight gain, or if your baby has lost skills they once had or isn't babbling, responding to their name, or sitting steadily. Trust your instincts and ask whenever something feels off.
