This week, the baby is 21 weeks old!

I had to take him to the doctor on Monday. All weekend (and on Monday morning), he had been grabbing his ear, rubbing it and it was very red. He woke up stuffy two days in a row, and hasn't been sleeping great. All signs were pointing towards ear infection.
Turns out, nothing was wrong. At least, his ears, lungs and throat were perfect. The doctor thought that he might be teething. He could also need a few extra calories. But he isn't sick.
That said, I paid a $25 co-pay to learn that he's 15 pounds, 14 ounces. Up 10 ounces in just under 3 weeks. (And the scale kept switching between 14 and 15 ounces, so he could have been an ounce heavier. He's a little wiggle worm.)
I've upped his bottle for the time-being to see if that helps him gain more weight (he's doing fine, though) and to see if it helps with his sleep at night.
Oh yeah. And on Tuesday, I received a text message from the babysitter. As the baby was gnawing on her finger, she felt the tooth that had cut through his gums. Poor baby. Interesting that neither the doctor nor I - and two other people - had felt it.
Early bedtime is still going strong. The first few nights, he was a little fussy when I put him down. Now, he goes down without a fight. The swaddle is about to come off, though, and the sleep sack will go on. He breaks the swaddle almost immediately when I put him in it. Silly boy.
So, big milestones for us this week. Teeth, breaking out of the swaddle, and no ear infections. :)
