DD has been PT'ing for a while now, and overall she prefers to use her little potty rather than the full size potty (with seat adapter.) Yesterday I was cleaning her potty and could not get it to smell clean! I couldn't figure it out, so I washed the entire thing, lid, base, bowl and the foam seat cushion. I finally found the source of the stench - that stupid foam ring cushion! OMG! It is supposed to be water proof, but the pee smell is imbedded in it! I've tried everything I can think of to get that smell out and nothing has worked. I'm afraid her potty is destined for the trash very soon if I can't get the smell out. I wish someone had warned me to avoid the foam seats! So, if you're potty shopping, do yourself a favor and stick to the plain plastic ones!
Re: What I wish I'd known about potties!
I'll add on to your post that I had a similar problem with the potty I bought. The potty has an insert that can be removed to use as a toilet ring and it took me a few days to realize the insert created a seam where pee could get underneath. Eww.
Pick your potties wisely!
We have one of the one piece o plastic- Baby Bjorn potties. Its great!
