I am trying to find some childrens clothing specifically boys. Toddlers as well would be nice. Seems like most websites I've been to only have girls or recolored base game clothing. :/

Plenty of boys clothes right here. https://www.modthesims.info/brow...dcategory=Child

And if you want to replace a horrible boys clothing for a nicer one then it's here http://sims2defaults.dreamwidth.org/

I agree with joandsarah77 that there are lots of clothes for children here, especially clothes by fakepeeps7 who specialises in clothes for children, toddlers and babies. Other sites worth looking at are Simphany.com (I'm always recommending that one) and The Sims Resource (TSR). TSR was a paysite until quite recently, and some people think it's slower since it became free. (It's adverts are very intrusive.) I tend to only use it for things I can't get anywhere else.

As male and female children have the same body shape, it is quite easy to use Wardrobe Wrangler to redesignate clothing to either sex, for example if you find a girls' outfit that you think would look as good on a boy.

Of course there are odds and ends of Sims 2 children's clothes on lots of other sites as well, though not usually with as good a selection. I found some I liked today on XM Sims 2. Searching for images on Google I find a good way to find clothes for my Sims.

Fakepeeps is easily my favourite clothing creator for sim children. Loads of clean, well made, bright, maxis matchy but nice clothing.

Garden of Shadows is good too especially if you like a slightly grungy, punky or gothic style.
