Oh, Cricket. So sorry about the foot. It is miserable to have a broken foot.
Broken bones are not fun. I stubbed my toe like Chris did. When I looked down at it, the little toe was sticking perpendicular to my foot. Being a girl, my first thought was that my shoes would never fit with the toe like that. So I grabbed it, stretched it out, pulled it into alignment and let go and it snapped back to where it was supposed to be. When I went to the doctor the next day, he told me I had dislocated it but he took an xray anyway. As it turned out, I had broken the one bone in 3 places, but the stretch and snap put it right. I could not wear shoes for about a month. It was November and I was wearing flip flops. Brrrrrr!
I imagine you might be off your feet a bit with a cast and all. Maybe you could turn this into a positive for Isaac by telling him it gives you more time to sit and do things with just him. You might put a basket together with fun, sit down activities to do (I Spy books, coloring books, favorite story books, Hot Wheel cars, crafts) while you are off your feet and tell him it is yours and his "special time" basket.
Anyway, hope you are all well again real soon.
