My 2-year old is going on a trip (4-hour airplane ride) for 3 days with my husband to visit his parents and my son's new baby cousin. He's never been on a trip without me, although he's stayed at our home with my parents for 2 consecutive nights. What have people's experiences been with toddlers traveling without their primary parent? I think I'm going to struggle with it a lot more than my 2-year old!
