Bday WWYD?

[nicolewi]

DS's b-day is 12/10 (turning 5), DD2 is 12/12 (turning 3), DD3 is 1/8 (turning 1) and DD1 is 1/23 (turning 7).

We do St. Nick on 12/6 (small stocking stuffers and candy), then bdays (family party on 12/12 for DS and DD2), then Christmas extravaganza with parties on both sides, and a family party for DD3 and DD1 on 1/9. Since they are close enough in age to share toys, they get the benefit of everyone else's stuff, too, but it's ALL AT THE SAME TIME. ALLLLL.

DS wants to have a friend party at a bounce place, and we told him we could b/c his big sister got to do that when she turned 5. 

We could have his party the week of Dec. 13, probably for a couple hours in the afternoon one day. But, he will be getting SO MUCH STUFF all at once and I am afraid of millions of duplicate gifts. But, it is still close to his actual birthday, so that is nice.

Or, we could delay it until the week of Jan. 11. Pros: separation a bit from all the other stuff so it's a little more exciting to get presents, and I would have different ideas to give anyone who asks. Cons: is it too far from his actual bday and weird that it's after the family party for his sisters' January bdays? 
As I write this and think about it, I'd really kind of prefer to delay it, but is it just too far from the date??

SECOND: 
Best time to have it is 1 to 3 in the afternoon. 
DD1 will be at school and will be MAD, but she will be at the family party, and the school party is with HIS friends from preschool, not anyone her age. Do you think this is okay? Or would you do it in the evening so she could be there? 

PS Another kid did the 1 to 3 time. B/c preschool is 9 to 11:30, there is usually someone (parent, grandparent, nanny) who could take them to a daytime party. 

EDIT: SHORT VERSION. Is it too far past the date if I have a friend party for DS in mid-January for a mid-December birthday?

I wouldn't hesitate to go to a bday party in Jan for a dec birthday. I would assume dec was too crazy. Generally a month out is a bit much, but I think dec bdays get a pass, just my opinion.

1-3 sounds good. But I don't have various ages of children.

Im with Sing. We see it a bit here with summer birthdays being celebrated early to involve school friends that may not be around for summer. I don't know an official etiquette answer, but I wouldn't bat an eye.

Another vote for would not think twice and prob would appreciate it since December gets so jammed up!

January is totally fine. I would want DD to be included though so I'd either do it at a time she could come or let her miss school.

Did you ask your ds when he wants to have it? Of he's okay with Jan I would probably do it then.

I would totally do January.

Another vote for January. Save yourself the stress, and worry about it in the new year.
