I am a child care giver also. I watch children off of Rock Crusher Road. Call me with your questions, but have a little advice. No one person is perfect. It sounds like something stupid happened while she was out of the room. I know for a fact that those things happen (not making excuses) I would not of EVER let someone in my family clip your children's nails, but the point is, from what you wrote, the sitter probably genuinely did not know, and later she was probably upset by your phone call and did a little investigating after everyone went home. It is respectable that she called you back, because believe me, scratches and things happen. I would talk to her about a better system with leaving the kids alone in the room, almost impossible to do, yet how old was the neice? Tell her to talk to the niece about not doing things that only parents generally do (clipping nails) and I am sure, the baby may scream like you pulled her nails out at home when you did it, but she may not of heard crying, but sometimes when you are in potty, when you get back to the room and check all out, it is usually nothing. Don't mistrust your sitter, if your kids are happy there. If boo boos keep happening I would call it kind of stupidity, and just choose someone else. Always give the benefit of the doubt, but use common sense. If you have any questions, or need a new sitter, I have several references, and will do my best. Always put your kids first and be comfortable with who you choose to put your kids with eight hours a day! Remember they are very impressionable and are in those delicate years. Make sure you choose someone who (mostly) does things the way you do. Plus, I have sweet kids/parents and have actually turned families down because of their obvious behavior (the parents) and the children's behavior. I have to have people come into my house and interact with my family also, so I am very careful who I subject my family to also. I don't want someone's unruly child teaching the children I already care for to be picking up on that bad behavior. I know some of it is expected, kids do stuff, but I am just saying to make sure that all is adding up, and keep yourself in check. If that stupid stuff happens a lot, tell her ok, and just quietly look for a new sitter. Sorry so long, hope this helps, C. ###-###-####
