Baby at week 33

With 33 weeks left, your baby has already: Skull bones still soft and unfused — allows passage through birth canal. Amniotic fluid at maximum.

Mother's body — what changes

With 33 weeks to go, your body is: Waddling gait. Ribs feel bruised as baby kicks upward. Increased vaginal discharge.

Nutrition & supplements

Add ~450 kcal/day. Increase iron and DHA — brain growth peaks now. Split meals into 5–6 small portions to control heartburn and stable glucose. With only 33 weeks left, focus on iron-rich foods to build baby's stores for the first 6 months of life, and vitamin K-rich leafy greens.

Safe exercise

Reduce intensity but keep moving. Pelvic floor + squats prepare for labour. Avoid contact sports, ski, horse-riding and hot yoga. With 33 weeks left, prioritise perineal massage, pelvic tilts and squats — active preparation for the pushing stage.
