i am nursing my third daughter. i nursed the older two just fine. my baby now is 5 months. all of a sudden letdown takes a really long time to happen. she gets mad and quits since letdown isn't happening. i kinda manually pump my breast to get it going but by the time it happens she is too mad and won't latch on. i'm frustrated! she will not take a bottle at all. i don't know what to do! i have a lot of milk.. just not sure why letdown is taking so long now! any ideas? thanks for any help!!
