I sent mine out this week for our December 14th party because I know people plan things for the holidays and I wanted to give plenty of notice. I sent mine via Evite which will also send reminders closer to the date as well as has an option to save that date directly to peoples calendars should they wish
I let people know we were celebrating from 3 months before but sent out actual invites 2 weeks before
Not got an answer but I’m thinking the same, my baby’s birthday is the 4th of December and I know loads of people have Xmas parties from November-January time! I’m thinking October time. It’s my SIL baby shower mid October so I’ve no clue when to do it if I should before of after🤦🏻♀️. I think maybe end of October/november may be best time for you xx
