He doesn't spend much time laying down to play now. If he's not crawling, he's sitting up and enjoying the higher vantage point as he plays.
I still do double takes sometimes when I see him sitting up. In the wee hours of the morning, this sleep-deprived mama had a "who is that?" moment when I found a child sitting in the crib and calling for me.
This stage and new discoveries and abilities is a fun one, but it makes me sort of sad to see our baby days slipping away so quickly.
I'm finding myself feeling sentimental about little things, like the fact that I need to buy some size 4 diapers for nighttime. Size 4! Violet was in 3s for a lot longer than this. I was reading an older blog post and realized he's only been in the 3s for two months! It's not my imagination...this kid is flying through babyhood.
