In the first 3 weeks after born my baby was Latching normal, now she is 6 weeks and in the last 3 weeks I can't make her latch well, she make this sound when she breastfeed, and I think that she is getting more air based on the bad latch. Why she doesn't latch the same ? I try to put all my nipple and areola inside her mouth but in some way she get only the nipple, I even try different positiosn. What I'm doing wrong ?
