It's a yellow sort of day

Surprisingly, both mommy and daddy where up before Liam this morning. He didn't want to get up and was snug as a bug in our bed. We went to work at the house again today. While playing with his duplos on the porch, Liam said "yellow" when grandma pulled out a yellow block. He also said "blue" when grandma asked him what color the blue block was. I think this was the first time that he said the colors of something. I taught him the names of common colors, but he hasn't used them before today.
