My mum decorated my old room in their house for when my son visits with me. They went with a jungle theme, which is good because I consider that unisex.
They got a Fischer Price jungle themed portacot with mobile from Target on sale (only $99 and DS LOVES the mobile), some jungle themed wall stickers from Reject Shop, Mum made some curtains from some material she got at Spotlight and found a cute jungle sheet set and some jungle themed toys

Looks great!
