9wo dd has started to fall asleep during every feed. She's ff every 3 hours during the day but over last few days has been taking an ounce and then falls asleep which results in about 45 minutes of putting her down, picking her up, calling her name etc to get her to take the rest of her feed. She only takes a max of 5 ozs per feed as it is and is slowly gaining weight. She's already on tommee tippee size 2 teats as she wasn't getting anything on the size 1s. As soon as you put her down though she's wide awake and smiling away. Every feed is a battle at the moment and I'm at the end of my tether. Any suggestions anyone??
