Thanks Leckert, I've been stocking up so have plenty (been buying a pack each time I shop), but wasn't sure how many to take with me.

Onyx - as short as possible, I want to be home for DS as soon as practical, but thinking if possible 2-3 days max. DS was in the SCN so I was happy to stay longer last time, this time I am hoping all is good and we can head home as a family pretty quick - Fingers Crossed!

So if I pack 2-3 packs I should be be right by the sounds of it (I can always get DH to bring some in, just needed a ball park!)
