I know it may not seem like swim weather, but if you have access to an indoor pool (or are in the southern hemisphere) you might think about cloth diapers for water fun, too!!
First, I would recommend checking with your pediatrician about what age they recommend for first water play (a quick call to the nurse line should do the trick). Even though M was born in the heat of August, our doc suggested waiting until 6 months old both because babies are better able to regulate their body temperature by then (which is why also we are advised to dress them in one more layer than we would dress ourselves given the weather) but even more she was concerned with the risk that M might swallow water (since baby bodies don't really know how to digest water until 6-12 months old)
|Here's what a swim diaper looks like|
In full disclosure, for water play days at daycare they still recommend a disposable (regular daytime one), so usually we send him in with a 'sposie and his swimsuit, slathered in sunscreen, and they change him back into cloth after Splash Day festivities conclude.
Also, in full disclosure, I have actually yet to experience the cloth diaper, er, doing its job, in the pool. I still have confidence in ours, and will continue to use it, since I can't see how a disposable version could possibly do any better a job at keeping solids in... I still worry. If you have put your cloth swim diaper to the test, can you share here?!
