Preparing for baby #2

Any tips for preparing our little ones for baby #2? I’m due in June and starting to freak out a bit. Like, how is my son going to handle the transition? How am I going to handle it? What do I do with my son if there’s any sort of complication? My mind is going a mile a minute, I’ll be 30 weeks soon and I think that’s my “oh shit it’s happening” mark lol.

Also, any one have a recommendation on a double stroller? Looking between the graco duo glider and the baby trend that’s similar. It won’t be used as much because we live in the country and I have a double jogger for walks and such, so I’m trying to keep the price lower
