Your Baby is About

At around 12cm and 110 grams — the size of an avocado — your baby is on the move. Limb movements are now coordinated enough to be visible on ultrasound, and the eyes can make slow movements back and forth even though the eyelids are still sealed. Ears are almost in their final position. The nervous system is making more connections and muscle control is improving fast.
Many people start feeling their baby move for the first time somewhere between Weeks 16 and 22 — it's described as a flutter, a bubble popping, or a light tapping. If this is your first pregnancy, you might not feel it until closer to Week 20. If you've been pregnant before, you'll likely feel it sooner. There's a wide range of normal here, so don't panic if you're not feeling anything yet.
Your baby's eyes are still fused shut, but they're not switched off — they're already sensitive enough to detect bright light through your belly. If a strong light shines on your abdomen, your baby will turn away from it. This is one of the first signs of the baby responding to the external world. They're already paying attention, even before their eyes have opened for the first time.
This is a great time to start thinking about your birth plan. You don't need to have it finalised yet — but starting the conversation with your partner about your preferences for labour, pain management, and the immediate postpartum period means you'll have time to research and adjust before the third trimester stress sets in.
Iron absorption increases in the second trimester as your blood volume expands. Eat iron-rich foods (red meat, lentils, spinach) alongside vitamin C to maximise absorption. Avoid tea and coffee with meals as they inhibit iron uptake.
