Building Arm Muscles

So here is Ben's foot. Sunday night he had a little incident and this is the result. Ben is such an active little guy and quite frankly we are surprised he hasn't broken anything sooner. We just had to laugh because it was such an innocent thing that caused this. He was running to the bathroom and he misjudged where the door was and smashed it either on the door or the door jamb. I'm still not sure which. He did a lot of screaming and after using the bathroom (finally) we elevated and iced it. I figured he would be good to go the next day because there was no bruising and it wasn't swelling.
The next morning he woke up and took two steps and he fell on his face. He still could not put any weight on it. I took him to the clinic and then x-rays and sure enough he broke it. So now he is in a beautiful little blue cast and even though he can get frustrated at times he is in good spirits.
The first night he asked me how we take it off so he could go to bed. And then last night he asked if could take it off tomorrow. At this point it has only been 4 days not the 4 weeks he needs.
He is adapting amazingly well and gets around just as fast as he did before (however his knees are starting to really bother him from all the crawling). My arms are getting stronger than ever because I have to carry him whenever we leave the house. It makes me very grateful that he is such a healthy boy and that this too will pass.
