Every person has their own reactions and limits to a child’s behavior–that is to be expected! My suggestions:

• Have adults agree that one adult with handle a situation, while the others step back. This will allow the child to focus on their interaction with only one person. (Children study and are aware of our patterns of responding to them.)
• Grandparents support your children, especially in the child’s presence!
• Remember the age and ability of the child. Two-year-olds are moving and learning, building safe relationships and trust in the world. Redirecting is one way to help the child transition out of a difficult situation.
• Positive reinforcement means noticing, enjoying, the positive and not aggressively responding to negative behavior. (A child will do what’s necessary to get attention, even if it means negative behavior). Works with grown children, too! What do you think? The fun is in the discussion!
