Chipped bone in right foot Can I walk on it or will it make it worse?

Two days ago I fell carrying my 2 yr old daughter. There was a sidewalk involved and a large hill. I fell forward and twisted in the air on my foot to avoid hurting my daugher. Good news is not a scratch on her. Bad news I chipped a bone on the outer area of my foot where the foot begins to taper in. I saw an orthopedic specialist and he said that it will take at least 4 weeks to heal and there is definately some soft tissue damage as well. As of right now my foot looks like one of the hobbit's feet from Lord of the Rings. My toes are bruised and whole right side of the foot is swolen. I know that I won't have a cast and they gave me a boot and crutches. My question is will walking on it make it worse? Will it lengthen the recovery time or is that just a given. I have small 3 kids and it is hard to be on crutches with them. I also stay at home and have grocery shopping, cleaning, and such. I have a high pain tolerance, so do I try to walk on it or not?
