Just wondering what your opinions are on the cot sheets... some people tell me only cotton, but others are saying flanelette are the way to go...??

She's due in August, so it'll be cold for a few months, which I think is why people are saying flanelette. We're co-sleeping at night for a few months, and if she does go in the cot it'll be during the day...

What was your choice? And why? Does it matter?
