Going potty in public


My daughter will be two next month and has been pretty much completely potty trained (at home) for a month now. We are still struggling when we’re not home though. I’ve been putting pull ups on her when we leave the house. She doesn’t ever tell me she has to go when we’re out somewhere and if I try to take her when we’re out in public, most of the time she just absolutely doesn’t want to try to go. I’m not sure if this is a normal part of potty training and what to do to get past this little issue.
