Hi there,my son is 4 and a half and im having such a problem to get him to poo in the toilet...i have tried not putting a nappy on him but he holds his poo in for days..tried sticker charts and bubbles...and putting him on toilet n waiting n waiting...he will use all his power on the toilet and show me he is trying to get it out but can’t....he always asks for toys when puts a nappy on and tells me he can’t do a poo in the nappy unless he plays with his toys n takes his concentration away from pooing...plz help
