These past couple of days, M2's been proving herself rather adept at wiggling.
As in, she started out on the Boppy on the left side of the couch...
and ended up like this (as I was searching for a corralling solution).
This was short-lived: overstimulation. Have a portable crib, but where to put it. (M moved back into the regular crib because she's "a baby", wants to wear "baby clothes" with the snap bottoms, and wear diapers even though she totally gets the potty.)
