Congratulations!! How exciting

I think twowhats list is great. Its all the basic things you will need right away. All the other items can wait...if you have time and are bored while on bedrest, then sure, do research and figure it all out now. But if its stressful to you, then there's really no need. You can research and buy (aka order online) those items as the need arises (highchairs, bedding, jumparoos...all things that you won't need for a few months)
