Hi! My SIL, who had a baby in December, just called asked me if my girls ever had really stiff limbs when they were infants. She went on to say that when her DD was first born her fists and arms seemed stiff most of the time, but they've just started noticing her legs will always be out straight out and stiff. She said her drs never mentioned anything at her check ups in the past but she is going to take her DD to the dr. to get it checked out. I was looking a bit online and CP came up, but I'm a little confused. I always thought that was diagnosed at birth and that it wasn't something that would develop new symptoms later on like that?? Does anyone know if it can present like that?
