Помогите решить! На день рождения к подруге (май) пригласили, а у неё ещё брат (январь) и сестра (март). Подарок только имениннице или всем?

Sooo my oldest kiddo got invited to one of her besties birthday party in a month. Now this is a wwyd situation.

Details:The messy mom (I've written about her before lol) is hosting an all siblings birthday. This is wild to me because yes I've heard of combo birthdays before but they're usually in situations where they are close together... These kids have birthdays MONTHS apart. Kiddos bestie is in May, older brother (11) is in January, and the younger sister (8) is in March. Now I've known this family for years. The younger sister I've literally saw her in diapers at prek pick up. But I'm not close with either parent to a point where we talk outside of arranging pick up and drop offs to my house (my daughter has never been to this friends house in 7+ years but that's another situation).

So my dilemma, do I get all the kids gifts since technically I know them. I was thinking small gift cards for the siblings and then my usual $50 budget for bestie. My husband says no way since kiddo is only a guest of bestie technically. Party is at a park so there really won't be any kind of separation for the kids from my understanding. Kiddo didn't go to bestie's party last year because the invite was super late and I had a wedding to attend so idk if messy mom follows etiquette about opening gifts in private. I don't want kiddo to feel awkward if other kids call her out about not getting siblings gifts but my husband doesn't see it that way and thinks i just need to send one gift for her bestie.So...wwyd?
