Does anyone have any advice on how to handle this situation. My ex partner and I split when my baby was less than a week old. Now she's 6 weeks old and he's demanding he has her (on his own) for a full day. She's only ever been breastfed (which I'm very proud of) and has not been away from me for more than 2 hours. I've told him this isn't possible until she's older but now he's threatening that if I don't express (I don't have anywhere near enough milk to express for one feed never mind a full day) he will give her formula. Please help???
