- Soft skull plates allow molding through the birth canal.
- body
- Ready for the outside world.
- hands
- Grasp reflex is strong — perfect for that first finger-grab.

what's happening in your body
You may feel emotional, impatient, and very ready. Stay calm — labor will start when your body and baby are ready.
gentle tips
- Walk gently and stay active without overdoing it.
- Try labor-promoting strategies your provider supports.
- Sleep when possible — labor can be long.
- Discuss induction timing with your provider if past due.
- Keep faith and patience — almost there.
what to expect next
Most babies arrive between weeks 38 and 42. If labor hasn't started by week 41, induction is usually discussed.
