Week 29 old
Week 29: your roughly 7-month-old is sitting steadier, exploring solids, and settling into a 2-3 nap rhythm. Here's what's typical.
In short
At 29 weeks (about 7 months), many babies take 24-32 oz of breast milk or formula a day plus 1-2 small solid meals, and sleep around 12-15 hours total with 2-3 naps.
🍼 Feeding
Roughly 24-32 oz of breast milk or formula per day (about 4-6 feeds), plus 1-2 small solid meals. Milk is still the main source of nutrition at this age; solids are for practice and exposure.
😴 Sleep
About 12-15 hours total, usually 2-3 naps with wake windows of roughly 2.5-3.5 hours. Always place baby on the 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 for longer stretches and may pivot or lean to reach a toy.
- •Many 7-month-olds pass objects from one hand to the other and bring almost everything to their mouth to explore.
- •Babbling often gets more varied now, with strings of sounds like "ba-ba" and "da-da" (not yet tied to meaning).
- •Around now, lots of babies start showing stranger awareness and prefer familiar caregivers — a normal, healthy sign of attachment.
Milestones to keep in mind
- ✓The next CDC checkpoint is the 9-month checkup; at 6 months many babies could sit with support and roll, so by now you'll often see steadier independent sitting emerging.
- ✓Around this age, many babies reach for things and babble — but the range is wide, so don't worry if your baby isn't doing all of these yet.
- ✓By the 9-month visit, the focus shifts to sitting alone, passing toys hand-to-hand, and responding to their name; this week is part of that build-up.
- ✓Every baby is on their own timeline — bring any questions to the 9-month checkup.

💡 Tip for this week
Offer soft, age-appropriate foods in safe shapes and stay within arm's reach during meals. Avoid choking hazards like whole grapes, nuts, popcorn, and chunks of raw apple, and never prop a bottle.
⚠️ When to call your pediatrician
Call your pediatrician if your baby has fewer wet diapers than usual, isn't gaining weight, shows no interest in people or sounds, can't sit with support, or has a fever of 100.4°F (38°C) or higher. Trust your instincts and ask about anything that worries you.
Frequently asked
How much should a 7-month-old eat?
At around 7 months, most babies take about 24-32 oz of breast milk or formula a day across 4-6 feeds, plus 1-2 small solid meals. Milk is still the primary source of nutrition; solids add variety and practice. Amounts vary, so follow your baby's hunger and fullness cues.
How many naps does a baby take at 29 weeks?
Many babies this age take 2-3 naps a day with wake windows of about 2.5-3.5 hours, for roughly 12-15 hours of sleep total. Some are starting to consolidate toward 2 naps, but the transition is gradual and varies a lot from baby to baby.
Should my baby be sitting up at 7 months?
Around this age many babies sit without support, but the range is wide and there's no per-week deadline. Sitting alone is a focus at the 9-month CDC checkup. If your baby can't sit with support by now, mention it to your pediatrician.
