Announcement ideas

Hello ladies,

Any ideas on how to announce to family? (Grandparents, aunts, uncles)

My original plan was to buy these little eggs we are announcing for Christmas, and have everyone open them at the same time, but my husband seems to think that immediately when we say people to open it at the same time they will know before opening it.

My other idea would be to give my mother in law this as a present

Or have my husband (he already knows) open a present in front of everyone with the announcement

Any ideas?

Thank you!
