We are on week four of potty training for my 2 yr 5 mth daughter. She has got the hang of using the potty for wees but will not do a poo anywhere but in her pants. Even if I know one is coming up and say to her repeatedly that poos go in the potty and you'll get 2 sweeties/stars etc, and she definitely understands, it happens in the pants. It is not as if she doesn't realise she's doing it either!! Is this common? Any suggestions? thanks!
