Lol cute picture.
My 7 year old son took a picture like that as well with his baby brother of 1 year old.
He put on a Pampers Cruisers size 7 that he wears anyway for bed wetting and he wanted to dress like his baby brother and take a cute picture.
I would share it but he doesn't want me to do so so I will respect his decision.
Also just a note that the diaper is a Luvs Barney diaper from many years ago so I assume this boy and the baby are full grown now.
I remember my baby brother wearing those Luvs diapers when he was 2 years old.
