Every single granparent has something different to offer the grandchildren. Your grandchildren's needs and preferences will chage as they grow and mature. Right now they need what the other granmother has. In the future they may need what you have. I know it hurts to see them run to someone else but keep letting them know you love them and treat them the way that makes you comfortable. In time they will come to appreciate you and value you as much or more than their other grandmother.

How do your children (their parents) react to you?
