I had an issue like this recently, although thankfully the poop was not running out of the diaper...just many very loose BM's every day. It took me a long time to convince the parents that it wasn't normal...they were used to it and jsut checked him more frequently at home. Finally they took him off lactose and it cleared right up. However, since then they went to the doctor because he had actual diahrea and the doctor just said all kids poop differently and not to worry! I still don't give him milk at daycare,..not sure what the parents are doign at this point, but I don't want to deal with frequent runny poops.
