My two Aunts had a baby boy who is 3 yrs old now. He calls the one that gave birth to him mommmy n he calls his other mother, mama! Also babies sometimes come up with their own names like meema, nini, mimi, many different names. Don't worry too much because it will all come together! Good luck with the baby's delivery n God bless all 3 of u!
Thanks we were thinking that 2
With mommy, you child will most likely drop that and just say mom around the age of 7 (that's around when mine dropped the mommy name. If you set on mommy though you could do mommy and meme. That's a tough one I must say :/
