Girls, has anyone experienced this? Soon I'll have to fly ✈️ my little one will be almost two months old by then. We'll be flying for a while and we'll just be the two of us ? I'm a bit nervous, actually, more like MANY nervous about how my baby will behave. Maybe you could suggest something, like how to ease the flight for the baby and for me as well? I would be grateful for any advice or personal experience ?
