My sons just turned 3 and we started potty training last month. He cracked wees straight away but we are really struggling with poos. He knows when he needs to go and will usually tell me or indicate he needs to poo but I'll rush him Off to the toilet and he won't sit long enough for the poo to come out so ends up pulling his pants up saying he's not ready yet and then will do it in his pants but he comes straight to me and kind of whines the second he's done it. I just don't know what to do, any help or advice appreciated.
