Lots of changes for Jackson in the last few days.

His first tooth is poking through.
He is starting to respond to his name.
He is taking notice of the cats and is very interested in watching them.
He was absolutely fascinated by the baseball game on TV last night and paid rapt attention for two innings.
He has stopped sleeping through the night, waking up around 3 or 4 in a really good mood and wanting to squeal with joy while his parents sleep.
