Let the baby cry...

So we went to the doctors for her 2 month check up...I hate going to the doctors for myself, and frankly I am not liking going with Eowyn for her appoinments any better. The doctor checked her over and then asked us questions, like how she's eating (the fact that she's almost doubled her birth weight in 2 months I think speaks for itself...), does she smile at you, does she make eye contact...that was all fine...then how is she sleeping? We proceed to tell him, that she's sleeping fine, once she gets to sleep, but she wants to be up from midnight to 2am...after that she sleeps for 6-7 hours in a row...the Doctor looked at us, especially my husband who was holding the baby and doing deep knee bends to calm Eowyn as she was a little fussy from the pocking and prodding the Dr. had done... I guess he saw "new parents doting on their baby" written all over us and proceeded to give us some advice. As I am typing I am following this advice and frankly hating it..."Feed her, change her and cuddle her for a little while, then put her to bed. If she cries, which she will, let her. Do not go in and pick her up. She'll cry less each night and eventually you will have a baby who goes to sleep when you put her down." Well, she's been crying for 15 minutes...more then she cries in a given week, total...well, maybe 1/2 the time she cries in a given week...I guess the good news is I am not crying...I hate this.
