Kids will be kids!
Maybe he will never be fully potty trained but don't give up just now. When Mitzi came in my life (resp. I came in hers, sorry!) she was already 4 y.o. and not at all potty trained. Now she is 9 and with a lot of patience and a strict schedule we avoid (almost) all accidents. And then... they are soooo small and their accidents are not a big deal (literally), at least not for me.
