Emma - I hear you girl! My mother is always offering to baby sit our DD for us. In fact, we had made loose plans to go out for dinner and my mum was going to baby sit but DH came down ill so we cancelled and I was told that we 'owed' her a baby sit! She has watched DD a couple of times but we don't want to go out for dinner and to the movies all the time (plus it costs money and there are other things to spend the money on). I just say no, we don't want to go out yet - but I definitely keep it polite because I do not want to alienate a potential baby sitter in case I do want one, iykwim! I know what you mean, i think people are excited and well meaning but i'm sure that they wouldn't be offended if you didn't use them yet! Good luck.
