Thanks, BoysAreLikeDogs, for that link to the old thread. I found the ECUK Yahoo group in there, which looks as though it could be a good source of support. If anyone else is interested, it is here groups.yahoo.com/group/ecuk.
In the last few days I've been getting a few wees in the potty every day, after naps, if I get there in time, and after feeds. DS loves sitting on it and looking in the mirror/playing with his feet!
That's a good point, Ondine, about not always using the potty. When we eventually try this out and about, it would be useful to be able to hold DS over the loo. Will have to try that again. He can't sit unaided yet anyway, so I have to hold him whichever way we do it...
I will definitely keep at it part-time and see where it leads us. If nothing else, it will get DS used to the potty and, with any luck, fewer pooey nappies! At the moment I'm washing more often than before as I'm checking all the time and changing after one wee to keep him dry, but if I can get used to his patterns and determine any signals, then that will make life easier.
