Help, DD 4 who we started to potty train at 2.4 still hasn't got the hang of doing poo on toilet. She initially did very well with the potty but quickly started to hold on to poos. On reflection I think we should have given up and tried again when she was older. We persevered though but were constantly cleaning pants and by 3.4 she had a serious case of constipation which was horrendous. She is now taking movicol everday, (Lactulose didn't help), but still holds on to poos. She can get very angry when we ask her to go to the toilet as we can see by her face that she is desperately trying to hold one in. She generally would rather not go to toilet and it gets to be quite a battle at times and yet other days she just gets on with it.( so we know she can do it) We really don't know how to move on and progress. We have done loads of praise, rewards, charts, reading and playing on toilet, ignoring accidents, being dissapointed, nagging, not nagging, leaving her to tell us when she needs to go (lots of accidents) We have tried every approach and just feel very fed up after nearly 2 years and still no end in sight.
