Since having children I've been quietly fascinated by the things that are gendered in children's clothes. Almost everything you can think of is either coded feminine or masculine, way beyond the 'obvious' classic gender stereotypes (eg fairies on girls' clothes, tractors on boys' clothes, pink and purple for girls, blue and brown for boys).
Almost all animals are gendered. Girls have cats, mice, horses, ladybirds. Boys have lions, tigers, dogs (apart from poodles), frogs.
Almost all fruit is for girls, but boys are sometimes allowed pineapples. Pineapples are clearly the most masculine fruit.
Almost all vehicles are for boys, but girls are sometimes allowed bicycles (presumably due to their lack of manly engines).
Even certain patterns are gendered, with polka dots for girls and stars for boys.
It's all so utterly bizarre.
