When did your child stop using a stroller?

My daughter just turned two and our second daughter is due in December. Trying to figure out if we will need to purchase a double stroller. My husband thinks that the baby will be in a carrier for the first year so we won’t need a bigger stroller, but I’m not so sure.

At what age did your child stop using your stroller? Would you suggest getting a double stroller for kids 2 years apart, or do you think we could get away without one?

Thanks in advance 😊
