Hi B.-
i don't actually have a suggestion as to how to correct the spitting up issue, but i woudl like to just point out that it is necessary to keep your child away from the pool area if he (or she) is prone to this. every time a child spits up in teh pool, barfs in teh pool or even if a tiny bit of blood is in teh pool from a picked scab or cut, the pool has to be closed for teh next hour and also shocked with additional chlorine with the filters runnign double speed.
so if your child does in fact spit up into the pool. you have now ruined it for the rest of the kids for at least an hour and also caused quite the commotion at the pool.
not trying to be nasty. just letting you know how the pools do it. i have taught swim lessons for years, and many of which had to be canceled due to similar issues with children. then noone gets the lesson and noone else gets to enjoy the pool.
so until that issue is resolved, it might be best to have your own basin pool in teh backyard until you can guarantee that teh spits ups are once in a great while, rather than a daily occurance.
