And I have no idea why. LB is 21 months old and we've been training for around 3 months now. I know he's young but he has continually shown progress, except for a few times when he has slipped backwards for whatever reason. At the beginning of April he was at the point where he was sometimes telling me that he needed to go and doing it on the potty, only having 1 or 2 accidents a day. And then, as of right now, we have had nearly a month of gradual back steps to the point that he's now only managing the easy catches (wake up, arrival) and won't even tell me that he needs to go. He also used to be pretty accurate if I asked him "do you need a wee" but now I think he just says no so he can go do what he wants. He has no problems with sitting on the potty and actually enjoys it, will tell me he needs a wee when he doesn't. I will admit to using the TV a bit too much, but I've started reducing it and actually using it as a reward for AFTER he's done a wee, and he seems to be receptive to the idea of this, although no real difference to success as yet.
He was wearing pants to nursery (3 days) but after the first week of regression we decided he was holding his wee and having accidents because of it (had been in pants for a good 2-3 weeks at this point). This doesn't happen at home, he just does it where he stands now.
The only thing this really coincides with is a massive increase in daytime sleep, to the point that he can have 3 hours in nursery, wake up at 2:45 and then be absolutely shattered by 5. It is very hard to get him to have a second nap (hasn't had a second since he turned 1) and we don't get home from nursery (I work there) until nearly 7 so there's no option of getting him to bed sooner.
I'm scared to put him back in nappies full time in case he gets confused, especially considering he hasn't worn a nappy at home (except for night time sleep) for 3 months now. The other times he has gone backwards, there have been other symptoms such as bad sleeping, lack of appetite, other aspects of development also stepping backwards, but this time this is literally the only thing. His speech and absolutely everything else is coming along very well (he can actually read numbers and recognise many letters).
Please help, I am absolutely sick of continuous puddles and cluelessness.
