Potty Training

I am beginning to feel as if Devin will never get potty trained. Devin had started off potty training fairly well at the beginning of the summer. I started giving him "naked time" each afternoon and he was starting to get the hang of pee and poop needing to be excreted in the toilet. He even pooped on the potty for a week straight! Then something happened. I don't even know what it was or exactly when it happened, but he started to REFUSE the potty.

I am torn between so many different methods. Do I take him out of the diapers even though he is refusing to use the potty or do I wait? Do I try giving him periods of naked or underwear time again (like at the beginning of the summer)? Do nothing and just wait for him to let me know when he is ready? The other issue is that he is not home with me all the time. He is at daycare/school most of his day. They offer him the potty there, but they are not pushing him. They will do a potty chart with Devin, but if he won't even get on the potty its kind of hard to do a chart......

By the time we get home I have to make dinner, clean up, do the Nebulizer with Devin, bath time, bedtime routine, etc. There really is no time!!! Ahhhhh!!!! Will Devin EVER get potty trained????
