Potty training issues

Lauren

My son will be 3 on 7/2 and the first 3 days he did perfect. No accidents we even went out to eat and stores and had no issues at all! Now day 4 & 5 he is having accidents left and right. Even when we’re just at home and the potty is 2 feet from him. What’s going on? What do I do? Any advice is greatly appreciated.
