Talk to your child about the different ways in which each of your children became a part of your family. And about the fact that you are now one big family. Tell him that each of the children is unique and you love them for their uniqueness, their specialness. After acknowledging differences and making the child comfortable with them, draw on similarities of everyone in the family-this will make the child feel like a part of the family. Say” We all love to watch Superman “; “We all love to go cycling on weekends”. “We all take care of each other when we are sick”. “I stay up for your assignments as much as I do for your sister”. This will help in bonding.
