I would say research for what your looking for in bottles, I'm going with Tommee, and Minbie (which is only found online right now) I'm hopefully breast feeding so the teets (nipples) are supposed to help with nipple confusion. I also heard Pampers are the best diaper, while Huggies have the best wipes. I did all sizes and we have a variety of sizes upto 3. Idk the stroller lol we just are getting a combo one.
