Yes, thanks everyone for all the useful information.

I'll let you know how we go.

One thing I've done is ordered some baby earmuffs from a website. I always use earplugs on a plane, as I hate the constant noise, and I don't see why DD's fragile ears should be subjeced to that either. It remains to be seen whether they will work and be comfy for her, but we'll give it a go.

We're also gradually increasing time spent using the wrap carrier, so that I can carry her around the airport in that, assuming we'll have to check the pram first thing.

Anna, your DS and my DD share a birthday. Yay for Anzac Day babies
