Double stroller HELP!!

Anyone have a recommendation on a double stroller? I will have a 1 year old by the time my baby is born.

Doesn’t matter if it’s side by side or in front of one another.

Right now I have the Nuna Pipa and the Mixx2 stroller. It’s a very expensive travel system and unfortunately their double stroller is an arm and a leg that I’m just not willing to buy.

I will probably have to buy a new car seat as well as a Nuna car seat won’t fit into any double strollers.

Thank you!
