Ten Little Babies and Babies by Gyo Fujikawa. Baby has spent hours examining the illustrations in Ten Little Babies, which is pretty impressive for a 20-month-old. He liked it so much I bought him a copy when the library wanted theirs back. I suspect he will like anything by Gyo Fujikawa and we need to find more of her books at the library.
My Daddy by Guido Van Genechten. This is a library find that Baby adores, because he adores his daddy.
