My sweet little Lou is already 8 months old!
He has two teeth now, but you probably won't notice them when you see him because he almost always has his tongue sticking out!
He is still perfectly content just sitting on the floor playing with toys. He prefers this over an excersaucer, or walker. I've seen him roll from his tummy to his back one time, but i've still never seen him roll from his back to his tummy. Probably because he is never laying down! He has been sitting up since he was 4.5 months old. Also, because he is still sleeping in his rock-n-play sleeper!! We are planning to finally move him to the crib in the next couple of weeks.
He still wakes up once in the middle of the night, then around 5am, and goes back to sleep until 8 or 9am.
He makes me smile!
