We are wanting to move our 34 month girl out of pull ups and into training pants. Sometimes she uses the potty, sometimes not. I think the issue is that she doesn't feel uncomfortable enough to stop want she's doing to use potty. The question is this--- I've done some research on waterproof training pants and reviews are either they leak/don't fit well or high cost. I have come across some custom fit (etsy seller will make them to her exact measurements) pants that sound perfect but are $14/pair. Guarentees no pee thrus, etc. Can afford it but that's a lot for undies! However DD is consistently 10th percentile on weight/height (is 26lbs with a tiny belly & bottom), so I'm worried that the non custom pants won't fit right and would just be a waste of money.

So-- get the sure expensive option or hope for the best on cheap gerbers? Normally I'm ok with stuff not fitting just right but I really don't want to clean up pee if I don't have to!
