Are u talking about the little curve by his knees?
@Jody it’s the one on the right it just looks really in
Normal! They don't have proper kneecaps yet, it's actually really gross haha
When he stands knees together, does his ankles touch? If not could be knock knees. Is common and children grow out of it. CMT1A could affect gait and muscles but doesn’t usually do that? If in doubt, I would check with your GP.
I have 3 toddler boys. This looks 100% normal to me. I kept sitting here trying to spot what you’re concerned about and I cannot. Looks like wittle toddler boy legs to me mama.
