Book excerpt: Babies wear diapers. Do big kids? No! Big kids use the potty! Every child's life is filled with milestones. Some happen easily; others need a little extra support. Artist and mom Maria van Lieshout has been there. Drawing upon her own experiences, she has created an engaging series of books that are just right for children on the brink of major changes and the caregivers who encourage them. Plus, this is the fixed-format version, which looks almost identical to the print edition!
