i had to potty train 2 boys... i took my crochet in with me while they "read" a book while on the potty.
is she staying dry all night? does she tell you she needs to potty? if she's not, she may not be ready for potty training yet. and expect her to back slide a bit too and have accidents. when that happens, just have her help you clean her up and say nothing more about it than next time she needs to try and get to the potty faster and that everyone just learning has accidents sometimes, she'll already feel badly and be ashamed, no need to make her feel worse.
nada. taking a break.
