My fil is dead set on our second baby being a boy. He mentions it every time we talk to him. He even joked that if it's a girl maybe we should trade her in. I love my fil dearly but this is really starting to bother me. Anyone have suggestions for gentle reminders that being dead set on a specific sex is not OK?

Hubby and I are totally on the same page. We're just grateful to have a second on the way and will be jazzed about either sex. And none of the rest of the family has mentioned anything. I just don't want to end up resenting my fil over something we don't have control over
