after swim

Maybe you can bring a thermoflask of warm water to at least wash the hair and sponge baby. Then do a proper bath at home after that.

Bring some warm water to damp the face towel to wipe your child. Dry your child and go home asap to have a proper bath.

then don't swim. seriously if i cant bath my child properly then i will forgo the whole thing cos my child is my priority.

will in be too cold if shower in toilet if no water heater 😞

No choice then shower in the common toilet
