I was not home that day, but I wished I was.
He was on our double bed and was sleeping (I think). He woke up and suddenly she (his mom) saw him attempting crawls. At 6-7 months of age, the crawls should be expected behavior.
Whether expected or not, it was a pleasant surprise none the less... It was GREAT.. :)
After that day, we are thinking of getting him a walker.
