Do you have to bring 2 presents to a party for 2 children if you only know one and not the other?

Yes, if you can afford it , it would be nice. If money is an issue, get the other child something smaller. Children don't understand why only one of them got a present. The parents throwing this party should have specified what to do on the invitation.

It would be polite to bring a present for both children, since both children are celebriating their birthdays together. Even if you go to a party with a friend and you don't know the person it is the polite thing to bring a present of any kind because it's a birthday party and that's what people expect for everyone not to come empty handed and bring something no matter what it is. Think about it would it be fair to give one child something and not give the other and how would that look and what do you think the other child is thinking? Once you answer that you will understand how it is respectful and the polite thing to do especially at a children's birthday party.

No, I don't believe it's required to bring a present for the child you don't know. It seems like it would be fishing for gifts to host a joint birthday party and to expect each guest to bring gifts for both children, whether they knew both children or not.

If you wanted to be especially nice, you could buy a gift for the other child, but I don't see any reason that it would be "required."

The families should set up tables for the gifts for each child, so that guests can inconspicously leave gifts at one, or both, tables, dependant on the children that they know. At least, I see this as the most convenient way to plan this arrangement.

After all, the child isn't going to think, "Hey, you know, I didn't get a gift from that person over there that I don't know..."

Bring only one for the one you know. Or bring a really small one ($1-2) for the one you don't know.

No. The party planners realize that each child has his own set of friends and family members attending.

Why would the party organizers want to burden you by having you shop for a gift for a child's likes and dislikes you don't know?!

No, bring a present for the child you know, the one whose party you were invited for.

Yes. Please bring 2 gifts. It would not be right to leave one child out.

How old are they? I am asking this because, if they are young (toddlers or up to 5 years old), you could bring a "small" gift for the child you don't know.

If they are older, maybe gift cards (same amount).

Just my opinion.

Yes...however the second gift does not have to be expensive. A token of acknowledgement. A card with a gift card will suffice. Ten bucks for a kid I think is fine.

Yes--it's considered appropriate to bring a gift for someone you don't know if it's a joint party. Don't feel obligated to get something large, even a $10 gift card is something.

Since they are Kids, I think you need to bring 2. The other kid might notice and say something.
