There are so many answers to this question, but without details, I'm reluctant to assume the context of a "stormy relationship"; however, it's important to try and mend your relationship with your parents. A few counseling sessions may help identify the issues that plague the relationship. The fact that your parents want to have a relationship with your child can be viewed as a good sign as long as their motives are pure. Leave nothing to chance but do make an effort to mend your stormy relationship with your parents. Your child will benefit from developing a relationship with your parents. This might be a good opportunity to teach your child about relationships.
