We have never flown with both kids, and our daughter flew one time when she was only 16 months old. Our son is a wild card, so I wasn't sure how he'd take to a new environment. Taking photographs to document our adventures is one way I create keepsakes to remember them by. Overall they did great. Well, our daughter did great... she's a natural traveler and nature girl. Let's just say the sleeping didn't go well for CJ, but he did enjoy new toys to play with and sights to see. It really helped to travel with my parents, sister and uncle. The more hands, the better. The kids were thrilled to have everyone around for several days. They were also thrilled when my sister and I baked our dad's favorite cake and surprised him with birthday greetings for his 70th Birthday.
