3 week old baby boy

We have just barely gotten through the three week mark and already we feel like our little guy is changing so fast. He was 7 lbs 1 oz at birth and now he is 9 lbs 6 ozs, so you can see that his favorite thing to do is eat (he gets that from me, unfortunately!). As paranoid first parents, we have been in to see the pediatrician three times already. First, we went in to have his belly button looked at because it hadn't fallen off yet and was bleeding a little bit. Second, we took him in for his routine 2 week appt. The third appointment was to check his left eye because it was getting "goopey" all the time. The ped said that it looks like he may have a blocked tear duct, but that it is pretty common and will most likely clear up on its own. Other than that, things have been going pretty smooth, we love being parents.
