Congratulations on your pregnancy! That's wonderful that you will be able to be home with your baby. I am 36 and have a 2 1/2 year old at home and I work full-time. It's a constant struggle because I would love to be home with him! I am lucky that my mother is able to watch him while I'm at work.
Websites are great sources of information. I personally love Pampers swaddlers and then we switched to Pampers Cruisers (did not like pampers baby dry) Huggies supreme are ok, but I thought that my son always smelled like pee when he wore them.
Bottles: I like the Playtex nursers. The disposable liners are great (especially when a bottle rolls under the bed/couch for a few days (yuk) then you can just throw away the liner and pop in a new one!
I loved breastfeeding, but I didn't produce enough milk to sustain him so I had to supplement. I think that my problem was that I didn't drink enough water or eat right in the beginning. That's really important for your milk production. Also, I would have bought a breast pump sooner to help get things flowing.
Good luck with everything.
