Friend brings toddler on beach trip, I cancel plans - AITA?

A planned beach trip with friends was canceled because one of the friends invited his girlfriend and their toddler.

This decision led to the friend getting offended and accusing the post writer of not being a true friend. The post writer has no issue with the girlfriend but does not want to hang out with the toddler all the time. The situation is made worse by the fact that the friend's toddler is allowed to pull hair and put sticky fingers in the face of the post writer's friend, who is on the spectrum. The post writer is now questioning whether they are the asshole in this situation. Read on to find out what people have to say about this controversial topic.
