Godmoms for Adopted babies...

For those who believe in godparents:

Is it overstepping my boundaries as an adoptive mom to give the baby a godmom or should the biological mom have a say or be chosen as the godmom? I have two very best friends who I wanted to give the title to and I wanted to make a onesie that says

“My mom chose me and now I’m choosing you. Would you be my godmom?” But I don’t want to offend the biological mom by any means.

What do you think ladies?
