LO is 21 months and has certain songs that she has started singing along to. She'll start off "Row row row," when she wants me to sing Row Row Row the Boat. And she'll usually say the last word in the phrase, like if we sing, "We're going to the zoo, zoo, zoo. How about you, you, you. You can come too, too, too." She's say "zoo, zoo, zoo." "You, you, you."
