My 4 month old DD has become quite a snacky feeder and also (possibly related) developed quite an annoying habit. During a feed she has started frequently turning her head away - spitting out my nipple and kind of rubbing it against her cheek. I wondered if it means she's full but she often wants to relatch and cries if I take her away from the breast. Any ideas what could be causing this? It's driving me a bit mad now.
