I've recently (Monday) started changed my baby over from 100% BF to about 60/40 BF/FF and she seems to take the bottle well and it's giving my nipples some long needed rest to recover. But since then she has started really screaming in the afternoon and evening even though she is fully fed, clean and comforted... The usual fail safe methods of calming her no longer work and she'll only calm down if she gets boob... Is this normal?
