Hiya

6 days, thats great!

I would be hesitant at putting a nappy back on him incase he ends up going backwards. It would be terrible to have accomplished so much for it to all go down the toilet (or nappy!!) Why cant you bring the potty? Im sure people would understand u having to lug it around. I know its not ideal. I was basically house bound for 2 weeks while I trained Jenaya. As they say...once u begin u cant stop! Goodluck

I he telloing you when he wants the potty or are you reminding him?  if it's you instigating it I personally would probably use pull ups or some such as you are likely to get distracted chatting with your mum etc and forget to remind him as often as you might at home one on one.  If he's telling you, I'd pull ups for any travelling A(in the car if it's over an hour's drive away for example and take it off when you get there & pop jocks back on him then in Grandma's loo so he learns where it is and to use it instead of potty (if you're not taking it)  you can get padded loo seat incerts in Aust (made in china so you probably have them where you are too, which can fit in an extra large zip lock bag and a large MUms always have them hand bag, for public loo use.) which my 18 month old has successfully used twice this week woo-hoo.    if you're out and about shopping etc pull ups are probably a good idea as you may not always be able to find a loo, how ever if he does tell you he needs to go I'd advise you to encourage him to pee on  tree (if no toilet around) rather than use the pull up as you don't want to encourage him to go backwards at this stage
