Baby BBQ invitation wording

Please help me word this :

We’re having a baby bbq to celebrate the arrival of our daughter. Gifts are nice but not necessary. If you truly want to give something please consider a contribution towards her college fund.

Is that tacky ? Better way to word to it ? We don’t really need more stuff. Second kid two years apart but if people want to give something we just feel like supporting her future education is better ...

Thoughts ?
