It tired Isaac out. I thought he was going to fall asleep, but then he saw one of the toys I had brought and perked up.
I also feel like we had a good time of communication at dinner. He ate the food I prepared for him (yay) and then I got out some left over fruit. He would eat some fruit and then would point at the fruit for more. After a while he stopped didn't point at the fruit and I knew he was done!
