You will be fine Katymac and so will your DD. She has worked so hard for this opportunity to further her dreams. Good luck to you both this weekend and next week. I hope the move has gone well for everyone else and your DCs are settling in well.
We have found one of those Sainsbury's cards brilliant if there is one nearby - it's like two credit cards - they take one and you pay credit on yours and they can spend it in Sainsbury's at the other end! Lots of trust that it's going on food, but I have found that food is a major priodty for DS with all that energy being burnt off and no money! Also recommend online banking so you can credit their account when they ring you from the checkout and say " I can't pay for my shopping!!"
Good luck to all the DD's and DS's going off - they'll be back before you know it!
