My must haves for traveling with kids! We used the double stroller when Fritz and Keldon were 2 & 4 on our trip a couple years ago with the gate check bag. This year we used 2 car seat travel backpack carriers to fit Fritz’s convertible car seat + Keldon’s booster seat in one, and the Doona stroller in the other (Doona also makes a branded one but this worked fine). We checked the car seat bag right away and gate checked the Doona. The feeding set is great for babies 6mo+ and toddlers! For luggage, we checked 1 large checked bag + 2 carry-on suitcases to fit all of our things, + a personal item (duffle bag) and a sling bag I used to a diaper bag — I will link these as well! For anything you don’t want to travel with (like a bassinet or high chair), babyquip.com is an easy to use rental service! We rented the SNOO for Wesley on this trip. LTKTravel LTKBaby LTKKids
