Moms with 2 under 2 please

Is the double stroller worth it? My son will be 21 months when my next is due in November. He is already running and walking about 1/2 a mile on his own. I take my LO on multiple walks a day so the stroller was always beneficial in the past. I also wore my son with the ergo baby for a year. Im tempted to just stick it out and baby wear until my son is better at walking a ton. Just curious on anyone’s input. We try to limit all of our baby gear. Less is more
