my 7.5 month old has had a great latch up until now. In general she latches beautifully except she changes the latch every now and then. What she'll do is she goes from her usual latch (bottom lip touching the outside of the nipple/areola and the nipple up in the back/roof of her mouth) to sucking the entire brown area in (my nipple is about 2inch in diamiter). So much that she's not even getting milk...i'm not exactly sure why she's doing it. has anyone else had this happen?? Anyone think of why she would do that? I'm not sure of how to discourage her. I don't want to say no while she nursing because i'm afraid of discouraging her from nursing and i don't want to do that. I'm already working on her biting. This doesn't hurt the biting does.
