One of my close friends keeps offering to babysit my 7 month old DD. I just don't feel comfortable with it. She has a 3 year old DD herself and she smokes with her in the car. (I have challenged her on this every time I've seen her do it). She also drives too fast (in my opinion anyway). I know if she was to babysit they would end up being in the car at some point. I'm sure she would look after my DD and she wouldn't come to any harm but I just don't want her to look after her. I worry that she might get a bit bored with looking after DD when the novelty wears off and that she might find having them both a bit stressful. Another thing is that her DD is pretty boisterous and she doesn't really make much effort to discipline her, so I do worry that she might accidentally hurt my DD.
DD stays overnight with my mum and also my sister quite often so it's not like I can say I don't want her staying away yet.
I know this might make me sound horribly judgemental and not a very good friend. I'm only outlining it to give a bit of background.
If I have something on she often offers to babysit. Up until now I've fobbed her off and said my mum is babysitting (usually the case anyway). I do wish I could just say 'no, I'd rather you didn't babysit'. There is no nice way to put this though and it would definitely affect our friendship.
