My son is obsessed with cats and kittens and would reject your crocodile pjs. Luckily, he also loves sparkly pink crap too, because apparently cats are for girls only, don't you know. Yes, the disloyal torture-killers of the pet world are obviously all cute and fwuffy and perfect for wickle gurlz 
I buy his clothes for each season in advance, to take advantage of offers and stretch the cost, and have been sorting them just now, as he naps. Everything is pastels or brights. There's a few navy items, but mainly because I love navy. I get what I like, what suits him and what I know he likes. He also has longish curly hair and the face of an angel (not biased, ahem). He is a very caring boy, and I get raised eyebrows when he gets a free choice of toys, he will run to the dolls and cuddle them in his arms, tuck them into bed, feed them, and so on. We were at a toddler class this morning and every single girl was wearing pink or lilac and flouncy stuff, and the boys were all in sludgy-hued 'bloke' gear. Well, except for DS in a peach and white striped breton, jeans and turquoise Converse. I found the conformity boring and depressing.
Things were just not this ridiculous when we were kids, were they? I mean, I know there was miles less choice and availability of clothes and toys, etc., but we just all used to run around in flares and polonecks with pasty shoes and bowl haircuts . If you wanted to look particularly feminine, you might go mad with a kilt, some plaits and a fire-hazard cardi some ancient great-aunt had badly crocheted, but that was it. And kids just played with whatever was available. Yes, boys would generally be the ones with cap guns and action mans (men?) and girls with a Girl's World (I wasn't allowed one, sob!) or dolls, but there was none of this bullshit about pink lego or science kits being for boys, or even stuff like sticker books being gender segregated.
There's nothing wrong with girls wearing pink, or boys playing with cars, but parents should just let kids like what they like and back the fuck off with their ignorant gender ideas. A lot of people say they think it's rubbish, but still comply with the stereotypes because they don't want their kids to get teased or whatever. Well, if all the people who know it's bollocks dared to act on that, it wouldn't be an issue (or much less of one, in any case).
