I've been on the lookout for things for our DCs (one is white and one is mixed but obviously I want our white DC to see that having brown skin is a good thing too) and I thought I'd share some things I've found and see what else people had found too.
Our nursery had a nativity set from Lanka Kade which had brown faces on people OTHER than the wise men, and this company also has a lot of dolls, and also some nice bits for kids' rooms e.g. astronaut, fairy decorations. I'm definitely going to get the nativity set for next Christmas and I think a doll for at least one of the DCs.
Chilli Melon do cards for both adults and children with Asian or black faces (many of the Asian ones are religious but there are quite a few that are more general and would work for many children with brown skin who don't have Afro hair).
I am currently on the look out for puzzles that have children of different ethnicities in the pictures as most of the ones with people on have just white people. Ditto things like card games/matching cards (both of ours are preschool age).
There are also quite a lot of good lists of books but I will leave it here for now and see what other people have to add? Some of our favourite books are Everywhere Babies, a Baby's Day book that came from Bookstart (there's one baby that looks exactly like our DC and the other DC gets very excited about this!), Ezra Jack Keats books, and Global Babies. There are a lot of books about lovely Afro hair too which we may get one or two of but that's not what either of the DCs' hair is like so it will be more of interest than personally a good example.
