Hi! My mom, sister and I are planning a shower for my older sister in May. We will be holding the shower at my mom's house.
We are unsure if we are supposed to invite the in-laws. We will definitely be invinting the MIL, but do we need to invite his step-sisters, aunts, grandparents, etc? Our side of the family is pretty large and would be about 25 people by ourselves. If we had any more people, my mom isn't sure how we would fit them all. Is it bad ettiquette if we only invite our side of the family plus the MIL?
