It is unbelievable how little Wally was on older picture, your sketch caught all recognisable features of Wally.
The video is really cute, it seems like Wally did not know how to play with such a little "snowball" but he was very careful and gently. Beautiful film and nice to see and your son too.
Thank you @stef1 for such beautiful and loving words :) . Yes Wally was very sceptical. :D :D
