sorry for the question, but I wanted some quick answers/advice. DS is 3 and a half. He mastered weeing on the loo earlier in the year, but seemed to be typical in that he would only poo in a nappy, not on the potty or loo. He had been getting a bit constipated/holding it in, so on the pharmacists advice, we started giving him lactulose. Three weeks ago he finally did a poo on the loo. This led to lots of praise, a special toy we had been saving until he did that (yes, we did resort to bribery - the reward chart or chocolate buttons had not worked), and he has done it a couple of times since (still with lots of praise). However, he's still on the lactulose but hasn't pooed now for 6 days. I'm going to try to get a GP appointment for him today, but I wanted advice. If the GP gives him laxatives, would it be a backward step if we put him back in nappies for the duration, or do you think he would be able to cope on the loo?
