Do you do this or is it completely unacceptable / egotistical? If your child has a positive relationship with a close family member, would you continue to facilitate that even if you yourself have become ill-disposed towards them?
My sisters had had a heated argument over a relative non issue (some mild insults bandied around - both had their fair share of blame, as far as I can see). One of has a toddler, and not long after, said baby crawled over to my other sister’s room and they were spending time together - they’re getting quite close. Sister comes over and basically snatches her baby away - ‘if you want a relationship with her don’t insult her mum’. Other sister is completely broken and says it’s violating the niece-aunt relationship which should remain intact irrespective of what happens between sisters.
Who’s being a drama queen here? I think there can be an instinct to keep your child away from people who have hurt you, but surely that creates trust issues if you’re switching relationships on and off in their life, with no consistency?
