My daughter is the same age and she is my third child..the boys were pretty easy, but she is taking forever! She understands perfectly what she should do and does most of her pees in the toilet, but poops are always in the pull-up. It doesn't matter if I put her in underwear...then she just does it in them and tells me. She knows she shouldn't, but just can't seem to get over the hurdle. I don't want to make it a power struggle, so I don't make a big deal...just remind her of hwo big girls go on the toilet. I may try putting her pantless for a few days, but only during non-daycare hours and not in the daycare area. I would NEVER let a dck go bare bottomed in my home and would never let my own kids do that in the daycare area either! It isn't sanitary and also as a parent, I would be pretty troubled if I saw naked children running around at my child's daycare. It is just soooo different from at home with our own families only.
