I'm planning a trip to visit family with my DS, who will be 3.5 months old by then. It will just be the two of us (DH is staying home with our daughter). Travel time isn't too long...we have about a 2 hour flight with a connection to another flight that should be a bit over an hour. Layover times each way are about 1.5 hours. I'm not sure if I should plan to wear him, or use the stroller. The connecting airport is fairly large. Any tips for flying with a baby this young are welcome! Thanks
