Scout's toothbrush, check, but toothpaste is too big to get through security. I'll borrow SB's paste if desperate.
Don't own an iPod or similar. 
Yes to moisturiser and face wipes.
Yes to sweets.
No need for specs/contacts and MrScout is in charge of his own. MrScout is also in charge of his own anti-seizure meds (though I did double check he had enough for the trip plus extra in case).
Bunny (and most likely Creamy Bunny) are currently being used so will travel separately. Baby Bunny and Baby Creamy Bunny (the newest addition to the warren -- joined us last month) will go checked luggage.
They don't seem to make plain Mini Wheatabix any more so can't get any for SisterScout.
Remembered to pick up Cottage/Shephard's Pie mix for MomScout. Got extra goodies for JM as well. Splurged on the newest Steam Train magazine for SB and MrScout to enjoy during take-off.
SmallBoy gave the veteran/Poppy Appeal volunteer £1 today and was so excited when he gave him one of these rubber bracelets that are all the rage now. "Watch, Mommy, SB got a watch!" He's so proud of that "watch" he keeps looking at it on his wrist.
Right, I'm going to go start loading the car (stroller, camera bag (x3), trains, carry-on backpack, bag of food stuff that needs to be packed into checked luggage and laundry I'm doing at PiL tonight). Gah, still worried I'm forgetting something. (Laptop will get packed later....)
