He is 4 and i have been trying to get him out of night nappies. He is consistently dry whilst he is here but when exh has him he insists of putting him back in them, which means that he wets the bed for the first couple of nights he is back here. He also gives him a bottle at bedtime and lets him use a potty during the day. It took me ages to get him to use the toilet! He undoes all my hard work and thinks its amusing. I've tried talking to him but he has always been petty and this is his of getting to me.
