this week's highlights
- Hearing develops
- Bones harden
- Taste buds form
- Practice breathing motions
how your baby looks
Limbs are well-proportioned. Skin is still see-through but a thin layer of fat will start building soon. Eyes are still closed.
body in focus
- head
- Tiny taste buds form on the tongue.
- body
- Practice breathing motions begin — pulling amniotic fluid in and out.
- hands
- Hands can grasp and clench.
- feet
- Strong reflex kicks against the uterine wall.
what's happening in your body
You may have more energy and clearer skin. Some people start feeling early flutters (called quickening) — like bubbles or popcorn popping.
gentle tips
- Talk and sing to your bump — your baby can hear your voice.
- Add iron-rich foods to fight anemia (lean meat, beans, spinach).
- Sleep on the left side with a pillow between the knees.
- Confirm the anatomy scan appointment for weeks 18–22.
- Find a comfortable pair of supportive shoes.
what to expect next
Quickening — those first tiny flutters — usually start between weeks 16–22. First-time mums often feel them later than second-time mums.
