I like the mockingbird because it’s very modular and I can configure it in lots of ways. It folds easily and has some great accessories.
The bugaboo donkey is a side by side that is also super modular and amazing. I have a few twin mom friends who love it.
What I WANT soooo bad is the wonderfold wagon. It’s not the best for tiny babies, but it’s GREAT for older kids because they feel a little more free in it. It also fits so much and is just really great. They have a 4 person one that I want when we have more kids. You can also attach, I believe, one infant car seat to it. Another one I know lots of twin moms having.
