Oh you poor thing Thrilled. Isn't it just horrible how someone can pressure us to go against something we believe in. I've been guilty of doing this too - it's so easy to do with such "controlling" people like your MIL. Don't beat yourself up about it, what's done is done. At least you know that you have the support of your husband and obviously your SIL understands too. I don't think you are being OTT. I don't know how you can manage it, but maybe get your husband to tell her that no one touches the baby without first asking mum or dad's permission and, NO ONE keeps mum away from bubs. I couldn't care less whether she was 3 weeks or 3 years, she's your daughter and that shouldn't happen.
