Sebastian's 4th Month

Here's what happened this month:

He loves to play peek-a-boo, even covers his face with his "blankie" by himself to play it
Still screams at the top of his lungs
Sits on his booster seat
He is rarely bottlefed, but if he does, he holds his bottle by himself
Smiles or laughs back at himself in the mirror
Sleeps on his side
Rolls over (both right and left side) without any effort but hasn't turned back yet
On stomach, lifts head up 90 degrees
Prefers human interaction to his other toys
Sleeps longer, and waking hours are also longer
Loves to suck his fingers
Drools a lot, and can even get his drool back up his mouth (eeewww!!!)
Tries to sit up when propped
Closes and opens fist at will
Two front lower teeth are starting to make its way out (I know, early, huh?)
2nd round of immunizations
Loves to watch Barney
Squeals in delight
New set of hair starting to grow (quite obvious)
Loves to "stand" as he bears weight on his legs when pulled to a standing
And with that, he loves to play "Ten Little Monkeys (Jumping On The Bed)"
He loves picture books, and enjoys story-telling/reading time
Loves going out
Has a variety of tones, and sounds (as if words)
Reaches and grabs
Chews! (He copied this from me one time)
