I actually love when the parents say "okay, you can stay here for the night" because the children will say "okay" and smile and wave goodbye LOL. It is annoying though how these parents can't just pick up their child and get them dressed!! I will sometimes say "Oh xxx, you can get yourself dressed nicely. Show mommy!" Sometimes it works and sometimes it doesn't. It's amazing the change in some children when their parents how up haha. I have one dc grandma who tells me all the time that she loves that her granddaughter never wants to leave but I can see that sometimes the dck is a brat to grandma and I feel bad for her. She is an angel here all day tho!
I also love when they say "thank you" at the end of the day. I have one family who is great at everything but they always say "thanks for babysitting" and it drives me crazy LOL but I guess it would be weird to say "thanks for being a good dcp" or "thanks for daycaring" everyday haha.
