Naturepedic No Compromise Organic Cotton Classic Lightweight Crib Mattress
We also bought the car seat with matching stroller caddy. I decided on the Chicco Keyfit 30 infant car seat after looking at the options on the market and reviews online. I also decided to go with the stroller caddy instead of fullsize stroller since the full size stroller is so heavy and I wouldn't be able to lift it if I needed to take the baby for a walk.
We also bought the Fisher Price My Little Snugabunny Cradle 'n' Swing after some research. It can swing in 2 different directions and had a lot of options. It also had a power supply instead of just batteries which will be a huge relief. :)
As we start using these, I will post more reviews on these.
