I’d do a stroller because depending on where you go wagons are not allowed unless like super necessary like your have triplets or quads haha. But if just get a double stroller or maybe even a single to double like an evenflo or graco
Wagons aren’t meant for newborns, the baby has to at least be able to sit up but a double stroller you can use the car seat for and go on walks or take the newborn in. Once your baby is old enough to sit up and what not then a wagon can be useful. Personally I have both and I prefer the double stroller but maybe once my baby is older I’ll prefer the wagon 🤷🏻♀️ my baby is only 8 months old.
Wagon all the way. I had a 2 year old and a newborn. My baby is 9 months old and we use our wagon a lot. They love it.
