Am potentially going to be visiting people in Sweden before Xmas but am not certain that taking our buggy on the plane will be manageable - I will be doing the journey alone with my DD who will be 3 months old, and when there we'll be staying in a hotel. We have a Baby Björn which she likes going in - am I mad to even think of doing the journey and trip with just the Baby Björn and no buggy??? (and whilst we're at it, would you mind me asking 'Am I mad to even consider such a trip at all?!' and 'Are pop-up travel cots any good in your experience?') Thanks :-)
