This is one of those topics which are hard to tackle because we are culturally programmed to believe children SHOULD have relationships with their grandparents and that we are doing something very cruel by putting boundaries around this natural relationship. Standing against this cultural expectation is the power of a parent’s protective love for their child. We can overlook some behaviour when we are on the receiving end, but if our kids get involved then our primal defences rise up. Trust that prickly down the neck, hyper alert feeling you have. Your gut instinct has spotted there is something wrong about grandma’s behaviour. Do you feel queasy? Do your shoulders grip, jaw clench, eyes narrow, do you strain to hear what she is whispering in your kids ears? Your badass parenting instincts need some respect, you are not imagining things, something dodgy is going on.
