I have a nearly 5 month old DD who I've exclusively BF until now. Over christmas she has become more irritable and is putting her fist in her mouth alot. She was waking once in the night but now has been waking twice. If she has more BF she seems to sick it up more. She cries in a screechy way when laid flat or even in a rocker but is happy sitting upright in my arms. I'm finding this difficult though as have poorly hips still as I had SPD and am on my own with her and DS. Can anyone offer advice, I don't know what to do. Thanks.
