My DS is 4.9, and guess what he still has accidents now.
Hes been on a potty training journey for 2 whole years, and while he has improved, and never poos himself these days (thank the lord) he still has issues with wees.
I think most of the time he's so engrossed in what he's doing that he can't be bothered to go to the toilet, so basically laziness. But I also blame DH and I, because after about a year of it, we were still having poo accidents, and I got really angry with him one day, thinking he should know better and I think I actually made it worse by having a massive go at him I think.
So anyway I feel like it's just a constant issue for us and has been for 2 years, I find I'm always secretly irritated with DS and I know I shouldn't be because if he could do it he would, but he's so bright and switched on in every other aspect of his life, I can't understand why he has this issue with wees!
Anyway a friend of mine has a 2.6 year old DD, she's cracked potty training in a week, and we sort of laughed together about my DS taking 2 years (at least!) but secretly in my head I'm cursing her because it's been such a drag on our lives!!
Anyone else?
