My son is 17 months old an i am or WAS so looking forward to the summer and all the fun that come with it, he is so much more matured that the beach and pool would be so much more exciting, but I'm a nervous reck bc this is also our first summer with T1. He is pumping with the Animas Ping and wears contact detach set. When u detach which I am supposing is what you do to swim ?? There is now a opening for crap to get in .. An 1. Sand at the beach?!? 2. Not to sound crude but pee and poo at pools (like great adventure water parks or such) there's a direct line for nasty germs to come through his site.. It's like a germ water slide when I think about it.. Through the hole down the tubing right into his little butt cheeks!! In sure I'm freakish out more then I need to but what does everyone do when Going to the beach, or water parks??
