When is it okay to bring LO to swim? Need thermal swimwear? Waterproof diapers? Where to get it? Thanks

https://sg.theasianparent.com/guide-buying-swim-diapers-baby-toddler/ U can check the above asian parent article regarding the swim diaper. Gmarket and red mart got sell. Those Swimming places that are catered for babies will also have. No need to buy thermal swimwear but it is a good to have. Thermal swim wear more comfortable and some will limit the amount o water entering so not so cold for LO. But usually we also never let LO stay in the pool for too long yar, maybe 20 min?
