World record holder for youngest walking baby?

I want to know if there is one because my lil bro started walking at 4 1/2 months and I think that's just crazy.|||did the baby crawl first if not there may be some sort of developmental delay in occurrence because there is a natural progression that infants fallow and usually if something is so out of order like walking so early there is a red flag so i would get that child into the pediatrician asap|||Walking at 4 1/2 months is physically impossible....|||I always wondered that too. 41/2 months is probably close to the record.|||Vishnu walked at birth (but he was a god).|||Ethel - that gave me a sincere chuckle! Thanks!
