Re the raspberry leaf tea - I've been brewing a nettle and raspberry leaf tea concoction in my teapot and then drinking it over the course of a day. I think the recommendation is to start with 1 cup and build up over the week to the whole pot.
I have a small wheelie suitcase but it's not got everything in it yet so Will have to reorganise once my baby bag arrives. (My bargain storksak leather Elizabeth off eBay which is currently having the zip replaced!)
I had PE last time so knew I could be in for a few days. We took 3 bags - incl a cool bag with drinks and snacks. Of course I didn't fancy any of it when the time came so had to send DH to M&S for rations!!!!! I used some of the other stuff but not all of it.
This time I will have the wheelie bag and the baby bag but there will be a 2nd suitcase in the car in case I end up in longer than anticipated: I will still take a cool bag with drinks and snacks but just a small one this time.... Even if the snacks are just for DH! Currently we have jelly babies, coconut water drinks and GF biscuits and GF cereal bars. Not sure I will bother with anything else, except perhaps one of those tiny robinsons squash bottles...... Water can get a bit boring after a while!!!
