For bottles, we found that Dr. Brown were the best. Our kids were very gassy until we switched to them.
If you want a real jogging stroller, I’d recommend the Bob. My wife and I got the Bob double jogger as a gift (we had twins) and it was fantastic. It is on the heavy side and is large (it’s a double… what do you expect?) but it is high quality and is very rugged. It’s also expensive.
Honestly, nothing can really prepare you for having your first child. You’ll reach extremes of fatigue that you never knew existed. But it’s a huge brachah! B’sha’a tovah!
