I m planning to travel for the first time with my ds1 (19 months) and newborn baby ( maybe 3 weeks old) to malaysia via emirates with mil.we have a transit in dubai n the duration in dubai is vary depends on the day n flights from 1 hr to 9 hrs. Is it okay for me with active ds1 and newborn baby to have a long transit so we can relax a bit or the 1 hr transit is better.and another one, do I need to bring my own carseat for ds1 and do i need to take it out for the transit?what i should bring for both my children in the flight n transit?stroller or sling better for the baby?
