HATE to be the bearer of bad news, BUT my guess is "mom" isn't feeling well because she's embarrassed by her child. My hunch is that this child is simply continuing the same behavior of entitlement that she does at home. A strong willed child paired with disinterested parent(s) or passive parents is not going to understand the rights of others, how to fit in socially or manage their emotions. It's a very passive form of child abuse. While the child was at your home, there's not much you can do. I think you tried the best you could. I might suggest that the parents be called and informed that their child is not welcome at your home, as her behavior is disruptive and causes problems with other children's behavior. I will caution that delivery of said message is delicate, but necessary, and I would front it with "are you aware that when your daughter comes over her behavior is very difficult". The next question any sane, savvy parent would ask, it REALLY? Tell me more type directions. IF the parent is defensive than, that leaves you with the tactfully difficult directive that, well I"m sorry you feel that way, but your daughter is not able to visit here. Does your husband support this, because it's really a chance for the child's parents to have others set boundaries for them, as their tacit exceptance of the behavior indicates that the problem is child REARING, vs. their approach which sounds like just child SUPERVISING. Having Hubby on board would also indicate that the child's ultimate welfare is formost, and not the poker game.... It's a strong hunch that wont' be the first complaint from other parents. GOOD LUCK!
