How do you deal with parenting styles?

I have a toddler girl that comes, she is a bit rough around the edges and has a ton of attitude! I can't believe the way she talks and some of the things she says and she just turned 2! But her parents are the exact same way, so it is no wonder! Super nice people but they just parent way different then me. This little girl rules the house, and throws the worse fits I have ever seen! I would not tolerate this behaviour from my own children and do not tolerate it from her when she is here. The parents say they just don't know how to deal with her!? She was up until 11pm last night panting her Dad said at drop off this morning! She had paint all in her hair! The dad said he got max 2 hours of sleep because she was up screaming for a bottle most of the night?! Now she is being a handful today, with good reason, I actually feel really bad for her! I often brush out her hair and do it for her because it is such a matted mess. Her mom says she won't let her do it and screams, but she doesn't throw a fit when I do it! How do you deal with this kind of situation? How do you handle other parenting styles? I don't think my way of parenting or how I run my daycare is the only/right way but seriously, up until 11pm and now I have to deal with her behaviour until nap time?!

I wouldn't deal with the behavior. Period. If she can't behave and is whiney and cranky due to lack of sleep, I would call the parents and let them know she is not prepared to be in care today.

Their lack of parenting skills does NOT mean you have to deal with the fallout while they go merrily off to work not at all stressing about it.

The problem belongs to the parents. Give it back to them.

I agree with Kelly ....parents need to buck up and be a parent .....

There is no style to their "parenting" How can people really be that stupid as to let their child, especially one so young rule the roost. If the child is unable to participate in a reasonable manner at daycare due to sickness or lack of sleep I would definitely call parents to pick up their child. As Kelly P said, you should not have to deal with the lack of parenting fall out. Wow

Thanks ladies! That is so true an I will for sure be calling parents from now on if she looks and is acting like she needs to go back o bed!!

That isn't a parenting style, that's NO parenting. I have no words!

yikes! sounds like the PARENTS need to be in daycare!!
