Is my newborn sleeping too much??

[blushingbaby]

Hi DD is only 4 days old but sleeps all the time. I have to strip her to her nappy/ change her nappy to get her to wake up enough to feed and I'm starting to get concerned that she's going to struggle bf if she doesn't start waking up more often. She only wakes up for feeds once or twice a day - the rest of the time i have to wake her and its very difficult to keep her awake long enough for a good feed.
DS (20mo) was totally different - awake most of the time and woke up screaming regularly through the night for feeds.
I'm seeing the mw tomorrow but just wondered what you think?
Any advice/ experience gratefully recieved.

ds was a bit like this to begin with and mw thought it maybe jaundice - does he look a bit tanned? sometimes they grow out of it after a few days.

My DN born nearly 2 weeks ago is the same. She was a bit jaundiced but just a sleepy newborn. My SIL strips her and opens the window to get her to feed every 3 hours (in the day) and 4 hours at night. Don't worry, she'll wake up in time :)
