Four Months Old

I can't even believe it.
She has doubled her birth weight, basically she's gigantic.
She can hold her head up by herself, roll over, wiggle towards a toy out of her reach, support all her weight on her legs (but she's so wobbly you have to support her obviously). She swats, grabs, grasps, and grips with purpose and coordination. And my favorite, she reaches her arms out to people she wants to hold her.
Development is so fascinating to watch!
