Taking Baby Swimming - A guide to underwater swimming
Build up to it - for younger babies and first time swimmers, don't do more than 3 or 4 submersions in 1 session, increase the number each week (or each day if you are on holiday!)
Cover the head - always ensure your baby is fully submerged, the water must cover their head. Be decisive and aim for about an inch of water above baby's head, leave them for a couple of seconds and then bring them back up to the surface.
Listen to baby - if they protest a lot, build up even more slowly. It's meant to be fun so take the lead from your baby!
Reuben isn't very keen on this but we keep persevering!
Piece of cake!
