Stroller or wear baby?

I have 2 kids who have started school in recent years. We walk or use public transport most of the time. I obviously plan on getting a car seat but I think it may be easier to wear baby this time around instead of always using a stroller. When my 2 were younger we had a double stroller, they are 18m apart, so that’s what I’m used to. I didn’t really need to use a carrier but this time is going to be very different. Any suggestions?
