We're flying to Hong Kong this August for a family wedding. After much dithering we've decided to take all the children (5 years, 3 years and 5 months), which we're aware is not going to be easy (12 hours on a plane, jet lag, hot and humid weather etc. etc). My parents-in-law i.e. on the other side of the family, have hit the roof and accused us of being selfish, unfair on the children and particularly of endangering the life of our 5-month old baby (lots of strong amotive language is being used to deter us!). My question is this - does anyone know of any research that shows that long haul flights can harm young babies (due maybe to reduced cabin pressure, poor circulating air quality and/or other factors) or does anyone have experience of this? I have known lots of babies make that same journey without any ill effects, but I would love to refer my parents-in-law to some concrete evidence (either way, of course).
Thanks.
