Needs for a Winter baby

sno&jmg

E was born in the end of March 2010 & our Spring was pretty warm that year, so she spent the majority of her first months in onesies & swaddled in thin receiving blankets.

This baby is due in December & I'm wondering what I'll need to prepare for that. Not so much clothes stuff, but things for sleeping, being out & about with the baby, etc. As I'm typing this, I feel like the answer is so obvious, but I'm just kind of stuck.

Thanks, all!
