Hi, I have 3YO GGG triplets so a little bit younger than your DD's friends, but hope I can help! Mine like having a card addressed to them, so definitely a card each? It depends what your budget is really? And what you normally would spend on DD's friends? For example, if you would normally spend £10 on a present for one friend, and only want to spend that on all 3 children, (bearing in mind your DD is closest to their DD) I would spend £5 on girl and £5 on the boys.
Sorry just realised the date - has the party been already?
Maybe a bit late but can you ask their mother? I know I don't prefer to have 3 bits of tat for my DTrips. I usually ask to give one present to whichever child has invited them or to give one thing they can share.
Everyone has different opinions about this. I have personally asked friends and family not to give combined gifts as they are two separate children. You wouldn't give siblings of a different ages one birthday present to share so I think the same should go for twins. Plus they probably have different interests too and wont necessarily to interested in the same one present.
dd3 has been invited to a party for triplets. The two boys are in her class and the girl is in the other y3 class. She is closer to the girl and I think the invite is mainly from girl. Just wondering what to do about cards and presents. I was going to give each child a card and box of malteasers, and give a unisex toy to share. Does that sounds okay?
