My DS just turned 3 yesterday. He's been in kindy since last September, he still cries hysterically when I leave but he does settle quickly (within 5-10min).
He barely eats at kindy. We've just started toilet training him and at home he's had only a handful of accidents and is even dry 9/10 times at night already. But at kindy he refuses to use the toilet to the point where they make the call to put a nappy on at sleep time and sometimes he'll wee in his sleep, other times he wakes up dry and continues to hold until I get there. It can't be good to hold on for so long.
He also has moments throughout the day where he cries and gets upset. The staff are great with him and he talks about how much he loves it but I'm at a loss on why he eats so little and refuses to use the toilet?
