Please help we’re in the trenches , 3.5 year old potty trained in wees but will not poo , started off withholding then we managed to do some poos in the potty but it involved hours and hours of and off the potty until he couldn’t hold it anymore . held it In so much got constipated so we put laxatives in drink from doctors But still even if it’s hanging out he will not just push it out he’s petrified , won’t even put a nappy on to poo in it it’s honestly ruining life atm can’t leave the house and all day is filled with him whinging alllll day but he won’t go then ends up pooing himself and cry’s …. He’s so stubborn it took ages for him to just agree to potty train so I don’t realistically want to go backwards as he is great with the wees and doesn’t even wee in the night nappy , it’s been 4 weeks of hell we have toilet seats. Steps , potty’s , sticker charts , rewards be really wants. Choc etc
