Hi Everybody:
   I have encountered several babies that have done just what this 2 week old
baby is doing: sleep through the night, then nurse lots during the day to get
their 140+ minutes in. As with this baby, they all thrived: smiled, peed,
pooped and gained weight.  The mothers were happy to get a long sleep, and the
trade-off was that the babies nursed all day. I believe that this is a
variation of  normal  and if the baby is fine and the mother is happy, let it
go. What's to fix if everybody is well? Warmly, Nikki
