My Hair by Danielle Murrell Cox. Ages 0-3. Board book. HarperFestival, June 2020. Review copy provided by my local library.
It gently sets boundaries ("My hair is mine / from curls to puffs / You can look / but please don't touch"). It includes lots of great vocabulary words, both hairstyle words (Bantu knots, braided, puffs) and non-hairstyle words (funky, snip, slay), making this board book a solid choice for early literacy storytimes. The trim size is a bit small for sharing with a group, but the pictures are simple and bold, so it could work. And add it to the growing list of board books that can help families who are not used to talking about race start a conversation with small children.
