...smaller and simple!
I would say something small and simple next to your bed is key.. it was for us. We chose a Graco Travel Crib.. it basically looks like a mini version of a pack n play.. without all the bells and whistles.. just the sleeping area.. and we LOVE it! It still does the 3 stage heights.. so hopefully we can keep getting some use out of it! I love how easily it packs up too!
