I bought the Nuna infant car seat for my son and I absolutely loved it. I’ll be using it for my second babe when she comes at the end of the year. I did buy the Nuna stroller when I bought the car seat. I thought I was a one and done child kinda person but here I am pregnant again. I wish I would’ve bought the uppababy vista to accommodate two kids! But I’ll be buying one eventually now.
For Car seats definitely make sure it fits in your car, we had the Maxi Cosi one and it made our front passenger seat unusable. This time we are going with a Chicco Key Fit. Strollers it depends, if you are planning for 2 kids 3 and under a single to double, if you are going to be out in the winter something with good wheels would be smart. We have a travel stroller (Bombi) and I love it as our everyday stroller because it’s small.
Also debating bw single Nuna stroller or double uppababy vista v2
I'm looking into the evenflo omni plus, my friend has it and she loves it It looks similar to the uppababy, but isn't so expensive (if budget is a concern) I think part of it will come down to the style and function you are looking for, I want one that has the bassinet for when they're little and the upright seat for when they're older as well as the ability to use the car seat:)
