Yes, I hadn't noticed that you said you've spent five months trying to train him. When he's really ready, you'll be able to train him in about a week - honestly! He needs to know when he's ABOUT TO do a wee or poo, and to be able to communicate this to you (in words or gestures) and to be able to manage his own clothes (easy clothes like tracksuit bottoms are ideal). If he's not really ready, you're just giving yourself and him a lot of hassle by trying. Good luck!
