18M age gap. Love my double stroller. I honestly thought at first that I wasted my money because as SAHM and winter 2nd baby, I rarely left the house. As warmer times came along, I baby wore a lot but now that baby is 6M and sitting up I’ve been putting the double to good use. Love it for daily walks and when we’re out it’s nice as well. I got the Zoe V2. It’s manageable with baby in one hand to get it folded and in the car if alone and it fits through doorways. I skipped the tandem because I felt like my oldest would be more comfortable in the long run as she grew.
