Sometimes when the noise level gets to much for Trenton, he will go to his room and play. (I manage noise level in the house, but sometimes his peripheral hearing is very strong that it doesn't matter if Barney is on Volume level 1 for Andrew, its just too much for Trenton.)
Trenton enjoys sitting on his bed and looking at some of his picture cards.
Everyday, several times a day, he still opens books and babbles. He is trying so hard to read.
