My sister in law (husband's brother's wife) Is due to give birth in June. The shower is being planned for the end of April. I have not been included in the planning and I haven't been asked about clearing dates. My inlaws family is very small and my SIL has one unmarried sister. My mom got her shower invite over the weekend (I haven't gotten mine yet even though i live in the same town). She showed it to me and i was very surprised to see that not only was it being held at a restaurant (when SIL specifically asked for a house shower) but the Hosts were Mom, Sister and MIL.

I feel pretty hurt that I wasn't included (at all) in the planning or asked about the date. Husband says i'm overreacting and that its her sister that is being inconsiderate. His mom probably isn't even really involved except for signing a check to the restaurant.

Thoughts?
