Feeding help!

Jennifer

I know, it’s the millionth topic on sleepy babies but this is driving me crazy. Lately I can’t get 5.5week old to stay awake long enough to drink more than an ounce or an ounce and a half. We’ve tried everything in the book: tickling her, undressing her, changing her positions, wet wash cloth on her, even running her hands under water and she still won’t wake up and if she does, she just stretches and falls back asleep. I’ve tried bottle feeding her instead of breast feeding her to see if it keeps her awake and no luck. Any ideas or any insight as to if she’ll grow out of this? My pediatrician has only said “work on getting her to take full feeds” I’m trying!!!!
