Rowan update - 4 months

Rowan is twisting on his side aggressively, and will soon be able to roll over. He strikes me as a particularly strong baby, and will try to pull himself to as sitting position when he's laying in my lap as I offer my fingers for support. He is gaining better head/neck control every day, though still has a bit of bobble going on. He just turned four months this week. Wow, where does the time go?
