We're heading out to Bangkok & Singapore in March & my biggest headache is how to get our currently 17 month old to sleep on the 13 hour journey. He usually sleeps in his cot & is used to falling asleep on his own pretty much as soon as we lay him down. We know from previous (thankfully much shorter) flights that he usually screams for at least half an hour if he cannot lay down to fall asleep by himself but is held by us. If anyone has any advice on how we could help our little one sleep on the flight we would be very grateful. Thank you!
