playing with babies

I know playing with babies is easy. i love playing with them. i taught 1 how to do a "big hand shake" which is a formal handshake. but after 5 hours of chasing 20 kids playing with 6 babies is hard since I'm tired. playing with babies are easy but try playing with 2 babies at the same time. they both wanted to play and sit on my lap at the same time. try having that after 5 hours.
