My daughter (2 1/2 years) started going to the potty and toilet about two months ago and it went really well for a while, with very few accidents even at daycare. Now since about a week she only goes if I sit her on the toilet, never initiates going on her own and she pees her pants almost every evening and has more accidents at daycare also.

Do I need to be concerned? Is it normal for kids to lose interest in going to the toilet once in a while? I try not to make a big deal out of it, but I wonder what I can do to make it better.
