Double stroller help!!

Going from one to two kids this summer! I’ve been trying to figure out what in the world to do about the stroller situation. My first turns 3 in May and baby #2 is due early July.

We have a bassinet stroller that grew with her through a little over her first year. We loved this stroller even though it’s bulky the bassinet part was so handy to have for her to nap on the go and we go on walks anytime we can. The bassinet part converts to a normal seat that can be flipped forward or backward and adjusted. Our 3 year old is way too big to sit in it now but it was our favorite stroller for the first year and a half ish so we held onto it. Then we got a jogger stroller from FB marketplace that was slimmer and more convenient for our neighborhood walks as she grew out of the other one and we still use it now. Then I have a Jeep AdventureGlyde stroller that stays in my car for on the go.

I am considering attaching the sit/ stand part to the strollers we already have for my 3 year old but she still loves to sit in the jogger stroller for neighborhood walks so then I’m thinking I do need an actual double stroller for both to sit. I have a Graco infant car seat/ carrier so maybe I should get a double stroller that’s compatible with that carrier and then can be converted as the baby grows.

My friend told me to just get a wagon for the kids but my husband thinks that’s super inconvenient and bulky.

What do you all recommend? I looked at MockingBird double stroller but it’s soooo expensive! Should I sell the ones I have?
