I've found a regular babysitter to look after my son for a few hours each week during the day. I thought it was going great until a couple of his toys disappeared and he told me he left them at her house! She lives miles away - a reasonable train journey. I hadn't made a rule that she shouldn't take him to her house as it hadn't occurred to me that she would. I suppose I thought it was implicit that she wouldn't do that without asking for permission. Now I'm worried as I feel she ought to have known that I wouldn't approve of it and she didn't tell me she took him there! Not sure if I'm overreacting though - should I terminate the arrangement with her right away or have a discussion and set some ground rules then monitor it? Its always possible that my son has got confused as he is only 2.5 but he seemed pretty clear about it.
