When To Let Baby Meet Cousins?

Hi all, first time dad here. I have appreciated so much advice and insight learned from this Sub. Thanks in advance to anyone who shares RE my question!

Our LO is 5 weeks old (3 weeks early) and by all accounts doing well. We feel so lucky and happy to have her, but one issue has come up.

Partner wants to introduce LO to cousins and maybe allow some holding. I have taken the stance that it is okay to briefly meet cousins so long as they do not hold or touch her until 10 weeks (based on what I have read this seems on the low end).

Cousins range from 2 years old to 14. I think it is too early to introduce the risk but I may be over thinking. If anyone else has thoughts, please do let me know. How did you decide when it was okay to introduce LO to other chdren?

Again, TYIA to anyone who takes the time to read & reply.
