I don't know how I get them to fall asleep together this close. Although they are now sleeping in the same room at night! Grant has now learned to ignore Nathan when woken up at night.
But when Grant does wake up at Nathan's cries, he turns on the bedroom light, climbs onto the crib and starts yelling "MOM" "DANY" and wakes up everyone. And no, I didn't spell that wrong, Grant can't say daddy.
