Week 7 old
What to expect at 7 weeks old: feeding, sleep, and development for your 2-month-old baby. Warm, range-framed guidance for week 7 of the first year.
In short
At 7 weeks, many babies are feeding every 2 to 3.5 hours, sleeping around 14 to 17 hours total across the day and night, and starting to give those first real social smiles. Every baby is a little different, so think in ranges, not exact dates.
🍼 Feeding
Around 7 weeks, breastfed babies typically nurse 8 to 12 times in 24 hours, roughly every 2 to 3.5 hours. Formula-fed babies usually take about 24 to 32 oz per day, often 4 to 5 oz per feeding across 6 to 8 feedings. Cluster feeding and a growth-spurt appetite are common right around now. Keep feeding on demand and following your baby's hunger cues rather than a fixed clock.
😴 Sleep
Most 7-week-olds sleep about 14 to 17 hours total per day, split between roughly 8 to 10 hours at night (still with night wakings to feed) and 4 to 5 daytime naps. Wake windows are short, usually about 45 to 90 minutes before baby needs to sleep again. Always place baby on their back to sleep, on a firm flat surface, with no pillows, blankets, bumpers, or soft toys.
What's happening this week
- •Around this age, many babies start offering a genuine social smile in response to your face and voice, not just a sleepy reflex grin.
- •Babies near 7 weeks often hold their head up a bit more steadily during supervised tummy time, though heads still need full support.
- •Many babies this age begin cooing and making vowel-like 'ooh' and 'aah' sounds as early communication.
- •Eyes are tracking better now; around this age babies often follow a slow-moving object or your face from side to side.
- •Hands may start to open more and stay unclenched for longer stretches as the newborn fist relaxes.
Milestones to keep in mind
- ✓By the 2-month checkup, many babies smile socially, briefly calm when spoken to or picked up, and look at your face.
- ✓Around this age, watch for your baby beginning to hold their head up during tummy time and making cooing sounds.
- ✓By 2 months, many babies follow a moving object with their eyes and react to loud sounds. These are ranges, not deadlines, but mention anything that concerns you at the 2-month visit.

💡 Tip for this week
The 2-month well visit is usually right around the corner, and it typically includes the first set of vaccines. Jot down any questions now, and after shots you can offer extra feeding, cuddles, and skin-to-skin to comfort your baby. Ask your pediatrician what fever or fussiness is expected.
⚠️ When to call your pediatrician
Call your pediatrician for: fewer than 5 to 6 wet diapers a day or signs of dehydration; any rectal temperature of 100.4°F (38°C) or higher in a baby this young, which is a medical emergency at this age; poor feeding, very few wet diapers, or no weight gain; extreme sleepiness or being very difficult to wake; persistent vomiting, especially if forceful; or if your baby never makes eye contact, doesn't respond to loud sounds, or isn't beginning to smile by the 2-month visit. Trust your instincts and call if something feels off.
Frequently asked
Is it normal that my 7-week-old still wakes up to eat at night?
Yes. At 7 weeks, almost all babies still need to feed overnight, and night wakings every few hours are completely normal and healthy at this age. Babies this young have small stomachs and need frequent calories. Longer stretches of nighttime sleep tend to develop gradually over the coming months.
My baby seems hungrier than usual this week. Is something wrong?
Probably not. A jump in appetite, more frequent nursing, and cluster feeding are common right around this age and often line up with a growth spurt. Keep feeding on demand. If you're worried about milk supply, weight gain, or your baby seems unsatisfied after most feeds, check in with your pediatrician or a lactation consultant.
When will my baby smile at me?
Many babies begin true social smiles around 6 to 8 weeks, so your 7-week-old may be starting now, or it may take another week or two. Smiling is one of the things the pediatrician looks for by the 2-month checkup. If your baby isn't smiling socially by that visit, mention it so your provider can take a closer look.
