Charaz, as you haven't registered the birth, you haven't officially named your son. You need to have a name that you are happy with, you are his mother after all. Can you and your husband agree on a name (perhaps the one you first had in the birthing suite) ?

The hide of your ILs. If they want a baby named after your FIL then they better have a baby themselves. Sorry, but I really feel for you and don't think you should be bullied out of a name you have chosen.
