Why I am scared for 2 months from now

She's only 4 weeks old. She's been able to move her head freely since birth, and has, to quote the doctors, "very good muscle tone." She loves to try to push herself up with her legs and experiments with motor skills all the time (she's pretty good at reinserting the pacifier with her arms/hands if she drops/intentionally removes it).

Something tells me she's kinda already figured out the steps to crawling and we're only waiting for the inevitable.
