Four Months Old

Where have the last four months gone?? My sweet baby is now 15 lbs 12 oz (50th percentile, 90th percentile corrected) and we have seen many changes this month.  It feels like Finn has been in a perpetual growth spurt for the last month, feeding constantly.  He continues to be a wonderful baby and still sleeps a lot during both the day and the night.  He has discovered toys and likes to watch and reach for toys suspended above him, but has not yet mastered holding toys.  He has started watching Cohen and is interested in everything he does and he loves any kind of attention that Cohen gives him, especially the numerous kisses (and tolerates getting stickers put on his head).  The best part about this past month is that Finn has become a very smiley baby and always has a smile and a coo for his Mommy :)
