My 16wk old has reduced the amount of time she feeds for - it now between 10-15 mins max, then she starts wrestling and crying until I take her off. She may then go back say 5 mins later for another 5 min max feed. She previously fed for 25 mins plus and there was never any wrestling, crying etc. In the night she feeds for a bit longer and generally without the crying. She is still doing dirty nappies. The thing that is worrying me is the crying and screaming, it's like she is frustrated but then doesn't want to keep feeding, and she has never done it before. It's very unlike her. Has anyone else experienced this? She's goes 4 hrs between feeds and had been going 7 hrs in the night but now it's 5 hrs. Thanks.
