Need advice. My husband’s family has never treated my son as part of their grandchildren. Now that I am pregnant with my husband’s child, they can’t wait for her to be here and want to do all sorts of things for her. Should I let them? Should they get to spend time with one and not the other. I feel (and my husband does too) that it will be unfair to my son for them to want to be apart of her life so vigorously but not his. What should I do?
