Potty training, I give up.

Last week we had our first attempt at potty training Harper, It's winter here so potty training consisted of, staying at home, heater full blast, with no pants. Day one resulted in a few accidents, day 2, 3 and 4 he was near perfect, we had a few issues (he didn't like jocks, numbers two's needed a little bribery) but the biggest issue of all, he is super scared of the toilet, and NOTHING I can do will get him over it. And did I mention, "But, no I'm not a big boy," his words not mine. If he wont use a toilet, I am not about to carry a potty out and about.
If you've dealt with a scary toilet, I'd love to hear what helped make it less scary.

Note, I realise he might not be ready, I'm happy to wait before trying again, but he will have to be out of nappies to attend 3 year old kinder in January.
