is this true if a 2 year old doesn't like me should i leave them alone for a few months then she'll like me again

It is not necessarily true that a 2-year-old will like you again if you leave them alone for a few months. Children's preferences and feelings towards others can change rapidly and are influenced by many factors. It is important to respect the child's boundaries and try to build a positive relationship with them through gentle and consistent interactions. It is also important to communicate with the child's caregivers to understand any underlying reasons for their behavior and to ensure a positive and supportive environment for the child.
