Week 25: filling out
Fat makes the skin smoother and pinker.
Your baby is gaining fat and looking less wrinkled. Hair has colour and texture, the nostrils open and the startle reflex is in place. The baby responds to your voice with movement or a change in heart rate.

How your baby is developing
- Fat fills out the skin, which looks pinker as capillaries form.
- The nostrils open and the baby practises breathing movements.
- Hair has colour and texture.
- The baby responds to familiar voices and sounds.
How you may feel
- Haemorrhoids and constipation
- Heartburn
- Restless legs at night
- Frequent urination returning
- Pelvic pressure
- Thicker hair
Haemorrhoids are common because of pressure and slowed digestion. Fibre, fluids, not straining and short walks make the biggest difference.
