Your baby is 6 weeks old — smiles are becoming more frequent, and those early coos are turning your daily routine into something that feels like a real conversation.
What's Happening This Week
Your baby's physical development is picking up speed. Head control is noticeably better — during tummy time, they can hold their head up more steadily and for longer stretches. Some babies are beginning to push up on their forearms, lifting their chest slightly off the surface. When pulled gently from lying to sitting, there is less head lag than a few weeks ago. Their legs are getting stronger too, and you may notice them pushing against your lap or a surface with surprising force when held in a standing position.
Sensory development is blossoming. Your baby's visual range continues to expand, and they can now follow objects moving in a wider arc. They are beginning to show interest in more complex patterns and may stare at things like ceiling fans, light fixtures, or patterned fabrics. Their color vision is developing, and they are increasingly responsive to bright, warm colors. Most excitingly, many babies begin making cooing sounds around week six — soft vowel sounds like "ooh" and "aah" that mark the very beginning of pre-language vocalization.
Emotionally, the social smile is likely well established by now, and your baby may smile at familiar faces regularly. They are becoming more expressive overall, showing displeasure as well as delight through their facial expressions and body language. Alert periods continue to lengthen — some babies are now awake for up to 90 minutes at a stretch. The six-week mark often coincides with a growth spurt, so you may notice increased fussiness and more frequent feeding for a few days.
Play Ideas for Week 6
- Coo conversations: When your baby coos, respond with your own sounds. Wait for them to "reply." This back-and-forth teaches the fundamental rhythm of conversation and shows them their voice matters.
- Tracking games: Slowly move a colorful rattle in an arc over your baby's head while they lie on their back. See if they can follow it all the way from one side to the other.
- Tummy time challenges: During tummy time, position yourself or a toy slightly to one side to encourage your baby to turn their head. This builds neck strength unevenly, which is important for balanced development.
- Touch exploration: Offer different safe textures to your baby's open hands — a smooth wooden ring, a soft fabric square, a slightly bumpy teething toy. They are beginning to process tactile information more actively.
What You Need
Six weeks of tummy time practice means your baby is spending real, productive minutes on their belly. A quality tummy time mat supports their comfort and encourages longer sessions. Ours are designed for exactly this stage — see the full collection at /collections/tummy-time-mats.
When to Talk to Your Pediatrician
Your six-week check-up is a key appointment. Discuss your baby's growth, feeding, and any concerns you have. Between visits, contact your pediatrician if your baby has not smiled at all by six weeks, seems unresponsive to sounds, or if you notice their eyes consistently crossing (occasional crossing is still normal at this age).

FAQ
Is it normal for my 6-week-old to eat more than usual?
Yes. Around six weeks, many babies go through a growth spurt that leads to cluster feeding — feeding more frequently, sometimes seemingly nonstop. This typically lasts two to three days. It does not mean your milk supply is low or that your baby is not getting enough — they are simply fueling a burst of growth.
How long should tummy time be at 6 weeks?
Aim for five to ten minutes per session, with a daily goal of 30 minutes total. Some babies tolerate tummy time well and can stay longer; others still fuss after a few minutes. Both are normal. Keep trying consistently, and it will get easier.
