We have one from when I had twins (7 years ago) but we used it for 3 years with them, and then for about 6 months with my other kiddies and it’s a bit trashed. We want to get a new one. Would you recommend one with a seat in the front and back, or two seats next to each other? I need it for city walking and the kids will be 1 year old and newborn when they start using it. It needs to last til they’re about 3.
