Bow Legged

Is this normal? My LO is 14 months old, and I am so worried about the curve of his legs! The pediatrician didn’t say anything at his 12 month appointment. I was going to bring it up at his 15 month appointment that is scheduled for the end of May. I’m just worried it could be Blounts Disease or extreme bow legged-ness that might need some sort treatment ASAP (braces, etc).

He started standing on his own at about 7 months and started walking without using help at 11 months. Sorry for the dumb question! I’m just so worried!
