Four wetting herself

Katie

Is it normal for my four year old to be peeing her pants every day? It seems like if we r out and about she will tell me she needs to use the bathroom. But when we are at home and she is watching her tablet or playing she doesn’t say anything. I do remind her multiple times a day to use the bathroom. Is she just being lazy? I did say something to her doctor but they didn’t seem to concerned with it. They sent me a article on potty training. I’m not quite sure what I should do or the next steps are. I did take her tablet away but she still peed herself. Any help would be greatly appreciate
