I have just been to pick up almost 4 year old preschooler (dc has been there since sept 2014, is happy, loves the teachers, no problems leaving him, happy to be picked up, has friends to play with etc etc). Teacher pulls me aside and said he had pooed on the floor behind the toilet and that he had done it twice last week (they weren't sure who had done it but now assume it was him).
Now dc has been toilet trained since August 2012 with no problems since. Although last week I discovered he has weed on the floor in his playroom (into a little box) and then tried to poo on the carpet upstairs.
What am I doing wrong? It's not a mistake, it's deliberate as he was pleased he had done it.
Background is we have a 6 month dc also, no jealousy issues, he gets equal attention and even said this morning (to baby) "you're my best friend".
