So my ex has DD (3) every weekend (against my wishes but we haven't gone to court yet so this is another story). Anyway, it's come to my attention that she is still sleeping in a cot at his house. I am aware she's still being fed from a highchair (the same we had when she was 6 months old) and she's come home wearing shoes which are 3 sizes too big). He claims not to know what to do but I've given him pointers and he doesn't listen. Apparently I am told I am a nagging, stirring b*tch. He simply won't listen. I am aware that shoes that are too big will damage her feet (so I have confiscated them) but could sleeping in a cot at 3 be developmentally damaging? I'm worried she doesn't have enough room. She has a proper single bed here.
