i started training ds (2.8) about a month ago. everythin went fine to begin with, he loved his big boy pants and loved going to pee in the potty.
problem is is that he won't go anywhere but at home. he won't go at grannys house, won't go anywhere in public and will hold it in until he wets himself or we get home, he also insists on being totaly naked when he does use the potty

he also refuses to poo in the potty and holds it in and shrieks until a nappy is put on him.
don't know what to do really. he knows when he wants to pee and poo but i can't spend forever in the house with a naked toddler, i need to buy food and stuff!
another thing is is that ds has just been on a 6 day holiday away with dh and dh had him in nappies the whole time so i'm back to square one anyway.
