Week 25 old
Week 25 sits right around the 6-month mark: solids may be starting, sleep is consolidating, and your baby is more social and mobile than ever.
In short
At 25 weeks (about 6 months), most babies take 24-32 oz of breast milk or formula a day, may be starting first solids, and sleep around 12-15 hours total with 2-3 naps.
🍼 Feeding
Roughly 24-32 oz of breast milk or formula a day (about 6-8 oz, 4-5 times). If your pediatrician has given the green light, you may be introducing single-ingredient purees or soft solids once or twice a day — milk is still the main source of nutrition.
😴 Sleep
About 12-15 hours total: roughly 10-11 hours overnight (often with one or two wakings) plus 2-3 naps. Wake windows stretch to about 2-3 hours. Keep the crib bare — back to sleep, firm flat mattress, no pillows, bumpers, or blankets.
What's happening this week
- •Around this age, many babies can sit with little or no support and push up on straight arms during tummy time.
- •Many 6-month-olds reach for objects and bring nearly everything to their mouth; passing things from one hand to the other is often just starting to emerge around now.
- •Babbling often becomes more varied now, with strings of sounds like 'ba-ba' and 'da-da' (not yet meaning a person).
- •Around now babies tend to recognize familiar faces and may start showing wariness of strangers.
Milestones to keep in mind
- ✓By the 6-month checkup, many babies can roll in both directions and sit propped or briefly on their own — ranges vary widely.
- ✓Around the 6-month checkpoint, look for your baby turning toward sounds and voices (consistently responding to their own name is more of a 9-month milestone).
- ✓By 6 months many babies reach for toys and show curiosity, leaning to grab things just out of reach.
- ✓Many babies show feelings clearly now — laughing, squealing, and looking to you for reassurance.

💡 Tip for this week
If you're starting solids, offer one new single-ingredient food at a time and wait 2-3 days before adding another, so you can spot any reaction. Always keep baby seated upright and supervised while eating.
⚠️ When to call your pediatrician
Call your pediatrician if your baby isn't bearing any weight on their legs when supported, shows no affection for caregivers, doesn't respond to sounds, isn't reaching for things, or doesn't roll in either direction by the 6-month visit. Also call for fewer wet diapers, persistent vomiting, poor weight gain, or any fever of 100.4°F (38°C) or higher.
Frequently asked
How much should a 6-month-old eat?
Most 25-week-olds take about 24-32 oz of breast milk or formula a day, usually 6-8 oz across 4-5 feeds. If solids have started with your pediatrician's okay, they're small tastes once or twice a day, while milk stays the main nutrition source.
Is my baby ready to start solids at 25 weeks?
Around 6 months many babies show readiness signs: sitting with support, good head control, losing the tongue-thrust reflex, and interest in food. Check with your pediatrician before starting, and begin with single-ingredient purees or soft foods.
How much should a 25-week-old sleep?
Around this age babies sleep about 12-15 hours total, typically 10-11 hours overnight plus 2-3 naps, with wake windows of about 2-3 hours. Some night wakings are still normal at 6 months.
