My 5-year-old girl is not fond of my brother's 13-year-old daughter. She was born in front of me and I was with her during her growing up years, and my best niece. How do I help bond them?

don't force your daughter to like her but gently create situations that will naturally help them bond. i guess your daughter senses your fondness for the niece and is jealous. maybe you could take them out for a movie together, or shopping, ask your niece to help your daughter with some fun shopping tips :)
