I owuldn't say a wimp, Spinle - I would say sensible, tbh.
we have always gone away - dh likes to travel. and when dd1 was a baby, it was ok. stressful, but not more so than with any baby really.
and then the issues started appearing and dh was in denial a bit, which left me dealing with it all.
we had some very stressful holidays, and then I put my foot down and said I wans't going anywhere unless he pulled his weight a bit more on the plane etc (to be fair, dd1 had always been very clingy to me, we hadn't wanted ot tackle it in a public place so she got to carry on etc).
but we have now fallen into a routine. 18 months ago we went ot Australia - that was a biggie, and one where i talke dot dh a LOT beforehand and nagged him, if I am honest, about it not always being me who organises all the children things - meals on flights etc (we had ot take our own), knowing where everythign wa sin the change bag, stuff like that.
these days, he is a little too organised for my liking
, and will ask about stuff before it is due ot happen - a different stress, and a good one.
dd1 is now at teh point where I don't worry about flights - no more than with any child. obvioulsy she has the potential to act up, but so does any 6 year old. she understands security, and putting her juice and bear thorugh the x ray. but it took a lot of work (and stressful security times) to get her there.
if oyu're not ready for it, dont do it would be my advice, looking back.
