Congratulations on 9 months! We're still a couple weeks away....
Ryan's army crawling too, and getting quite quick at it, so we've had to start babyproofing again. He's not sleeping well lately, which I think has to do with learning to army crawl. He wakes up several times a night and when I go into his nursery, he's army crawling all over his crib! Luckily a quick nurse puts him right back to sleep. He's napping well, though - 1 hour in the morning and 2-3 hours in the afternoon.
He's eating some finger foods now like crackers, Cheerios, chunks of banana (he likes to hold a big piece and gnaw on it), and small pieces of soft fruits like pear, mango and avocado.
We don't have his 9 month appt until April, but I'm guessing he's over 20lbs by now. He's fitting very well into his 12 month clothes, and has completely outgrown many of his 6-12 month things.
