DH and I took in a few bags of small chips and also some soft lollies. For drinks we took gatorade in and we just popped them in the fridge until we needed them. I did eat during my labour as I had an epidural but before that I was eating ice chips and didn't feel like eating.

Maybe for Shel (if she likes them) maybe you could buy some of those tuna and biscuit packs to keep in your bag?!

Ps. Good idea with the separate bags. I had separate ones so it was great when DH could take all that stuff home.
