*ETA: Also: who, gets to claim the "donation" on their taxes?
And, what if... after your daughter receives and sees the "gifts"... she changes her mind and wants to keep some of it??? After all, the party, is for her Birthday. And after all, she is a young child.
Also: what if, the invited children/their parents... wonder if: if they do NOT bring a "donation" gift, then can they still come to the party? Or is it ONLY for those that want to donate? I mean, this is a Birthday party. Not a donation party. And some might think that they can only attend if they bring a donation and they might feel odd, if they do not participate in donating. And they will feel odd if they come empty handed.
Also, some might bring a donation "gift" and ALSO a Birthday gift for your daughter. Then what?
I have seen, this happen.... at donation parties that are actually a Birthday party.

Why, do you even have to tell the other kids, and that CPS is for kids who got removed from the home without their toys? Putting it that way, is so specific and wrongly so... and makes it sound like CPS is evil and mean, to kids. So why, would your daughter want to donate her gifts to them?
Just say your child has decided to donate her gifts, to a charitable organization that helps children. SO that, the parents of the invited children, can then decide for themselves, if they want to donate, and (2) if they agree with it and (3) so they can therefore decide on what type of "gift" they will get. If they ask, then tell the parents it is for CPS. And then the parents of the other kids, can explain to their own child, what CPS is. Because there are many other ways, to explain what they do.
You also: have to make SURE, that the CPS in your area... does indeed take "donations" like that. ie: toys.
Or not.
