Ugh! Why?

I think I may be on the verge of loosing my mind. For the past couple of weeks my 2 year old keeps having accidents. He's been fully potty trained since a couple of weeks before his 2nd birthday! Yes, he was the one to initiate it not me. He was the one refusing diapers. I've been done with diapers for a good 2-3 months now. He was doing well and surprised us all. However, now it seems like no matter what he still has accidents throughout the night and at times during the day. 

For weeks I have felt like an awful parent because my son kept wetting the bed. I tried remaining calm because accidents happen. Three weeks later and I think I am about to lose my mind. I can't keep up with so much laundry and its frustrating when I know he can go, but just goes about it without going. I would give him a friendly reminder about the potty, he'd say he didnt need to go and not 10 minutes later he was wet. 

I lost it every time even though I fought to remain calm. He is barely 2 and a half. Most 2 year olds are just starting to potty train. I should give him a break, so I googled potty training regression. I learned that most toddlers dont stop having accidents until months and sometimes years after they are trained. 

Things like having too much fun while playing or simply forgetting can be the main causes. Accidents happen. I've observed my son. I've noticed he mostly wets himself when he's tired. He no longer naps so when he's roaming around in his exhausted mode he tends to forget the potty unless I remind him. 

To get him back on track I've decided to put him back on the potty break every 2 hours and limited fluids. Like everything else its going to be a journey. He's not sick nor a failure therefore I should not make him feel like so. Rather I should encourage him and uplift him to get back to where he was. Every  day he learns and this is no different!
