Heath has been working on numbers with Ben. So when they're playing they're always counting things. Heath will say the numbers and Ben will repeat some of them. And when Heath gets to 10 he always says, "Yea!"
Last night I was giving Ben a bath and he has letters and numbers that stick to the side of the bath. So I was grabbing ones that floated by, sticking them to the side and saying what they were. At one point I grabbed eight and then Ben said, "Eight, nine, 10, Yea!" Then he started repeating, "Ten, yea! Ten, yea!"
