So sorry that this is happening to you and the girls.:ghug3
You have already received great support and ideas from the rest of our family, and I want to offer another idea:
Stay-Cation Wonderland.
Turn your living area into a fantasy world (tents, stars, fairy dust - whatever inspires them)
rent movies,
play games, I loved to draw on myself and my kids with washable markers,
sidewalk chalk,
try new recipes together
And don't forget the sprinkler in the backyard! (my personal favorite
)
