My son will be 8 months next month and I'll be travelling for 17 hours.. my flight is at 1am, he is usually sleeping by 830-9.. I have to leave to the airport around 9.. do I just came him awake and hope he falls asleep on the way to the airport and in his stroller? He doesn't have any teeth yet and now I'm scared he would be teething during the flight.. plz give any tips
