I started potty training DS (2.5) about 2 months ago and he got it pretty quickly with wee but refuses to poo in the potty. We've had success with a couple but only after serious encouragement and chocolate button rewards. If I catch him doing one (very obvious straining whilst grabbing sofa/table/shelf), I'll ask if he's doing or needs a poo, but he just says no and will get upset if I try and encourage him onto the potty.
How can I get the poo out of the pants and into the potty??
