Me and dh are booking our holiday to North Africa this year with dc's who are 4 and 16 mths plus me being around 30 weeks when we fly. Does anyone have any tips or advice for a 4 hour flight with other small kids in tow? Would have booked later but ticket prices too expensive for us now and want to visit dh's relatives before I pop. Next time we see them won't be for a few years til we can afford it again and youngest is at least 2/3 years old. Views appreciated!
