So I've just about figured out what I can take through airport check in...

[Callisto]

...but what about calpol sachets? I want to have a couple on the flight just in case DD gets a temperature but don't really want to take a bottle due to weight. Or can I buy them once we're through security?

You can put them in a clear plastic bag and take through security or buy from Boots other side.

Thanks, good to know we can buy them there if necessary.
