I like my wagon. I haven't tried it with my infant seat yet though.
I love my baby trend sit n stand 2.0. There’s a lot of variations so it’ll adjust to various stages and has decent under storage
And it breaks down smaller than my single stroller did
We bought a convertible to a double stroller as our original expecting to have at least two. Mine are 18mon apart and honestly the double stroller has been probably our biggest money waste. My oldest refuses and prefers walking or being carried. We did get a wagon and I would suggest that instead, if you need something. Obviously, this opinion is dependent on the kids personalities.
Honestly, I would recommend just getting a wagon, especially if you plan on having more than two kids. I wish I had gotten a wagon instead of a double stroller when I had my daughter which was my second and now I’m pregnant with my third and we are getting a wagon. I’m getting the keenz wagon
Some of those wagons hold a infant carseat
