Stupid question lol

I have a haircut appointment tomorrow. I’ve rescheduled it twice already because my husband needed to use my truck and I had no other car to go in. My mom was going to watch my kids but she went out of town for an emergency so I have no one to watch them for me. I don’t want to cancel because it would be the third time canceling and not only am I embarrassed but I know how annoying it must be for them to loose a client. Anyway my question is should I just take my kids? A 2 year old and 7 month old. They stay still but I’m just not sure if people do that lol!!
