That is so cute! It was always one of my favorite things when the kids found their toes and were so interested in them. Wiz found his the night before we went to Disney with him (trip to Fl to see my Gma when he was 11 weeks). Next day many things were less interesting than his toes unless Mickey was on them.
What a great stage!
It also reminds me that J used to crawl in with husband and I as soon as we were asleep. For two years I woke up with her head on the back of my neck and husband woke up with her toes in his mouth. Eeeeeeuuuuuuuwwwwwww! Esp for him. AFter the second night he insisted she get a bath at bedtime, lol!
