Two Diaper Bags?

Wondering if anyone else with two kids carries two different diaper bags? My son will be 3 when baby comes. I know most moms only use one mainly for the baby, with a few toddler items. However it’s more difficult with my son because he has a severe peanut allergy, meaning I need to carry food/snacks as well as his Epi-pens. Along with diapers, change of clothes, etc.

I feel like two kids and two bags is going to be hard to deal with, but idk what else to do.
