2nd thoughts on baby name

So before we even found out we were having a boy we were decided on Caleb. Our family has been asking us what we are we going to name the baby and we keep saying we don't know yet.. His sister knows Caleb was our favorite name so she keeps blabbing it out and his family keeps criticizing it and his mom especially keeps saying what is up with you guys picking a weird name. Ughh I really don't appreciate being told my baby's name is weird.
