it could be health related or summer related. my son is 3 1/2 and now that is is summer and he is outside playing more he comes in running but by the time he goes he has a small wet spot in both his underpants and pants. may be you could put a potty outside and remember to remind her. i usually remind my son when he askes me for something. he has to go potty first. then he can have whatever he asked for. it's working for me. stay strong and cosistant good luck and god bless!!
