We are planning on having DD christened in a month. The big question is who to ask as godparents.

My sister (sis 2) has asked DH and I to be godparents to her DD. It would be easy to ask her back, but am worried that other sister (sis 3) would be a bit put out. We have taken it in turns to me maid/matron of honour at each other's wedding so it makes sense to continue that tradition.

If we do ask sis 3 to be godmother who do we have as another godparent? She has a long term boyfriend (living together) but I am not really willing to ask him to be godfather as they aren't yet engaged so there isn't any really long term commitment. I would be willing to ask DH's sis to be another godmother but he thinks it would be a bit weird to have 2 godmothers, but no godfathers.

Any suggestions? Has anyone had 2 godmothers?
