my 2.5 year old daughter was actually reluctant to share her toys or things with other kids but this problem worsened when my niece who is 4.5 yrs visited our home and stayed for 5 days the new member was adamant and she was never ready to share the common toys or her grandma with others as she was little older among both she expressed her disagreement through dialogues and actions. the quarrel between both girls became a big headache to all of us. but she leaved the home now but after a few week my daughter is expressing her disagreement using same words and actions which my niece used and that too with other kids who visited our home. I am very sad will these characters continue for a long time
