PIL & Baby’s first time(s)

How to deal with PIL who always want to be with us for baby’s first time(s)? Keyword: always Baby’s first time go school, baby’s first time go zoo, baby’s first time go aquarium, baby’s first pool experience.. etc, etc. Not that they can’t follow us to outings but please, there are times when I just want me hubs and baby to spend the time together. Baby’s first time(s) are pretty special and it makes me feel like… I don’t even know what to describe. Always want to be there with us anywhere. And what makes it worst is that hubs is a mama’s boy. So… every time it’s a OK with whatever she wants.
