Yes, my son really did say that! It was only in reference to my successful assembly of Myra's bouncy seat, but still. It was nice to hear!!
We try to be positive whenever he does something well, or helps out - like with the mowing. :-) We usually say, "Good job, Logan!" and he hears it often enough that he says it to himself whenever he accomplishes something. It's pretty funny to hear it, especially since half the time I have no idea what he did... Anyway, it was especially nice to hear it directed at me!
