Hi, I went to check up on my baby and he wasn't using his left leg, when I held him up to check I noticed that it is very swollen and purple, it goes from the back of his foot and all the way up to his body. I felt for broken bones but couldn't find anything and he still moves it, just doesn't use it. I don't know how that happened but he does have a habit of jumping from high places even though I removed most of the stuff where he could climb to jump.
