I know this is a common problem but 2.7 ds has been holding in his poo for nearly 3 days now. He keeps saying he has tummy ache or says he wants a nappy on but we've tried to persuade/bribe him to use the potty. If he's wearing pants he'll just go in them. I came to the conclusion that a solid poo feels the same in a nappy or pants but wees are more uncomfortable in pants so maybe that's why he's cracked the weeing. But what can I do about the poo? Should I give in and put him in a nappy for his poo then take it off, let him poo in his pants until he gets it or risk getting constipation from holding it in whilst being bottomless? Any thoughts much appreciated.
