Yep Amelia was 13 months and we had a 4 hr flight each way. I'm not going to lie, it wasn't much fun. She won't sleep unless she's in a cot or her car seat so she was over tired and full of mischief. I packed new toys for the flight. She had crayons, little stacking look through blocks, a book, plastic animals and a pram fan. I also found nibbles passed the time. She got through a load of raisens, cherry tomatoes, cheese, little sandwiches etc. We took her for a couple of walks up the aisles when she was bored, but saved them for close to landing time as otherwise that would have been all she wanted to do. Luckily for us our flight had spare seats so the crew moved us so that she had a seat of her own which was a life saver. The other passengers were really good at entertaining her too!
Oh yes and I wore bracelets as she was and still is obsessed with them. I made a complete tit of myself by wearing them on my ears, head, feet etc
