I have fond memories of boarding a plane alone with Oscar hanging out of my legs, Emma screaming in the sling and then being told we'd be on a bus out to the plane, not boarding immediately...and had to get out my magic bottle - of course it was in a container filled with only 100mls but it was gripe water and calmed her down enough to survive the boarding, the walk to the bus, plane etc till I got O settled and could feed her in peace. Feels like a million years ago but has to be less than 4 ;-)
