Leg question

jen302

My daughter last week out of nowhere started trying to avoid standing on her right leg. If I go to put her down, she curls up her right leg. She does eventually stretch it out and stand on it. She doesn't seem to be in any pain, she moves her leg, and wiggles her toes, so it's not like anything is broken. Could it just be that she is just being lazy and all of a sudden doesn't want to stand? The only other thing I thought was maybe she was playing on the floor, tried moving (she isn't crawling yet) and maybe pulled something. It's the oddest thing to me. She has her 9 month well visit on Monday. So I will mention it to the pediatrician. Just curious if anyone has thoughts.
