No matter how hard it hits, being emotionally attached is not the same as emotionally available. Finding ways to emotionally connect with your child is necessary no matter what. When children grow up, they evolve, develop their own identity.
Though they carry attributes of their parents they're not an extension of your identity. So when you treat your kids as humans with a separate identity. You truly know them, rather than assuming stuff about them. Building a true relationship with anyone required patience, understanding and love.
