My two are 18 months apart....we went for the graco double, one in front of the other. The baby was in the seat that can snap on and off and works as the infant car seat and the older one sat in the front seat...the carrier is in the back seat until they are old enough to sit. This stroller was a life saver, as an 18 month old is still a baby and the sit and stand they can fall or they get tired. We had trays for both seats and a huge covered hood as well. Used this stroller forever for everyday and travelling....still used it even when they were preschool for travelling. Passed it on to another Mom when we were thru.Well worth the investment! You will be happy! Have fun with the two babies! They grow up so fast...mine are 2nd and 3rd grade now.
