FirstWeeksYour baby at 25 weeks: six-month runway
Medically-informed · Sources: CDC · Updated June 2026
Strength everywhere: sitting firms up, feet are discovered (and tasted), and the pre-solids appetite runs hot.
What’s happening
Sitting solidifies
Longer solo sits with hands free for toys are commonly seen around the half-year mark.
Feet join the toy box
Grabbing feet and pulling them to the mouth is peak flexibility — enjoy the acrobatics phase.
Sleep pattern check
Two-to-three naps and a long night block is the commonly seen shape; if nights wobble, it's usually skill practice or the upcoming teeth.
What to do
- Book the 6-month checkup
- Baby-proof one level down: floor-level cables, plants, small objects
- Photo idea: the foot-in-mouth pose does not last
When to check in
Loss of any acquired skill — always a pediatrician call.
