DD1 has 1 godmother
DD2 has 2 of each
DC3 will have 2 godmothers and 1 godfather.
We are atheists. Our families aren't very religious so won't be pushing their beliefs on anyone. But should the DCs decide, in later years, to follow a religion they would have godparents. I've had two nephews who have gotten confirmed even though they were raised as atheists.
