Hmmm must be the age cos we are having similar issues with that here too. I know how frustrating the screaming can be and also the pulling at your top saying "boo bee" every 30mins or so!! LOL it's very tiring at times. I reckon some days if DD wasnt offered food she wouldnt care as long as she has her booby milk !!
DD still wakes every 2-3hrs most nights wanting boob to comfort her too. (no matter how often we feed during the day time!) you aren't alone!

I don't have any advice sorry.... but am interested to read other posts.

Hang in there, this too shall pass xx
