My twins walked at 9 months, which would be 7 months corrected as they were 8 weeks early. They were about the size of a 6 month old baby. They were my first children and to me it was normal, I couldn't figure out why everyone would stop and stare at us when we were out and about. I suppose it would be weird to see babies that size up toddling around. LOL On a side note, my brother and i both walked at 7 months as well. I guess it runs in the family! Have fun!
