When to get help
Baby moving less than usual? HealthHub says: “If you feel that your baby is moving less than usual, monitor your baby’s movement for a while. If you are worried, see your doctor or go to the hospital immediately.”
HealthHub’s signs to act on, from 25 to 37 weeks:
See your doctor
- Headache and swelling of limbs: if these are severe or associated with dizziness, vomiting, blurred vision or upper abdominal pain
Go to the hospital as soon as possible
- Abdominal pain: regular, painful and persistent uterine contractions or tightening of the abdomen
Go to the hospital immediately
- Vaginal bleeding: bright red bleeding (like menses), or blood-stained mucus with painful contractions
- Reduced foetal movement
- Leaking of water: a continuous flow or a sudden gush of clear fluid from the vagina
How big is your baby?
About 36.6cm long, head to heel. NHS compares it to a head of cauliflower.
Leave and Baby Bonus
Coming up from week 30: tell your employer about maternity leave. Give at least 4 weeks' notice before your leave starts. For leave from week 36, the default start, tell them by week 32.
Which baby scheme applies follows the actual birth date. Born before 1 April 2027: the Baby Bonus Scheme. Born on or after it: the SG Child Support Package.
