Waking Tessa Up to Eat

So the doctor told us last Monday (4 day old weight check) that we need to wake Tessa up every 2 hours during the day to eat. So I have been. Now this is NOT an easy task...pictures below taken at "feeding time".

I took the swaddle off, and yet she still sleeps. This time I ended up just putting her back in her pack 'n play and waiting until she decided to eat. Today I am taking her back to the doctor to see if she has gained enough weight so I can stop all this "waking up".
