Which means never at nursery, public toilets, his childminder's or other people's houses where he sometimes goes either with me/DP or while I'm at work. (DP works nights)
He goes happily at home and has even started going alone now without insisting one of us sits in the bathroom with him. He is 3.7 and only fairly recently stopped using nappies for poo, about 3 months ago.
This is causing a problem in that if I'm at work for a few days in a row, he only has a few hours at home each day, sometimes a much shorter time, and if he doesn't feel he needs a poo during this short window, he just doesn't go for several days and of course gets constipated. :( It's awful as he wakes up screaming at night with it and sounds as though he's really in pain. We have started giving him calpol for it which seems to help with the tummy ache, but obviously it's not solving the real problem.
Does anyone have any suggestions which might help? He's perfectly happy to go for wees in all of these places and is really confident with that, it's just poos. Might he just get there by himself or is there something we should be doing to encourage him?
