As it turns out, both of them enjoy sleeping alot, pooping, and feeding every two hours. An as shown in the photo, both sleep with their mouths gaping open, catching flies while they catch some z's.
The other photos are Tia and Grayson in the nursery, and Grayson having some "Tummy Time". This time is supposed to help baby develop stomach muscles, neck muscles and control, and prepare them for crawling. Grayson just slept. Oh well, maybe next time.
