I have two annoying ones right now too, maybe even three if you consider our new angry screamer who shrieks in between getting spoonfuls of food or if he doesn't get something he wants right at that instant. And it is pure anger. And sooooo loud! Like its the end of the world.

The other two are girls who are part time and occasional. The part time one comes two days a week, she is 3.5, is ALWAYS odd and reaching out her arms to her mom at drop off, then she warms up, and goes about her day like she's mute and doesn't want to leave when her mom picks her up, kicking and screaming sometimes when she has to leave. She doesn't talk even though she is perfectly capable. Bites my own daughter in secret, and when she wants things like milk in her cup she just hands it to me. not asking ever. or hands me the empty one into my hand once she's done. All without ever saying a word. how rude!She especially likes to try to get your attention and decides to start talking to you and telling you unimportant things when adults start up a conversation, such as parents picking up their kids. She is a horrible eater. I have to spoon feed her to get her to even put food in her mouth. And when she does finally start eating she chews each spoonful for 3-5 minutes before she allows you to put in another. aargh. I try really hard not to feed her, I tell her she's a big girl and that the 18mth olds are feeding themselves and that I know she can do it too, but she stays with us for dinners and so there is usually only about a 15 minute bracket for her to eat between her getting her food and her mom picking her up. So I often don't have a choice but to, otherwise her mom stays and does it for her! So its useless even if I didn't!

The 3rd, she's very antisocial and has the craziest throwing herself down onto the floor and screaming tantrums. Only comes 3 hrs once a week thank god. And wants to be left alone in her playpen after about an hour of play no matter what new activities I suggest or try to do.
I'll be glad when they all move to new places. These are definitely children and clients I have learned from that I will try to omit, though all the families themselves are awesome to work for and amazing themselves.
I'm starting to find a pattern and think that the nicer the families, the worst their child is. Has anyone found that as well? I would really like to think this is not the case.
