Everything sounds normal to me! They seem to just feed, sleep and soil their nappies for the first month or so! As long as she is feeding well and normal poos and lots of wet nappies then I wouldn't worry!! Definately don't wake her unless it has been an unusualy longer than normal sleep.

They will let you know when they are hungry. If you are really not happy or unsure then just give your MCHN a call and run it by her!!
