Just looking for some advice. DD is 8 weeks and has taken the odd expressed bottle from a Calma teat but she really struggles to get anything out of it - it took DH 90 minutes to feed her 60 mls yesterday. I have quite a fast let down so don't know if that's something to do with it - should she have faster teats? I don't want to do anything that'll jeopardise bf but do want her to take the occasional bottle. Anyone in a similar situation or have any recommendations for teats?
