We like the name Dominic but my MIL hates it and keeps calling our baby name dumb dumb. She says that the baby will be teased (by others growing up) if we go with that name. Is dumb dumb really a teasing name that comes from Dominic? Can you think of any other names that Dominic could be teased with? Obviously we don't want our kid to be teased. Kinda sucks that she's making us second guess our name choice but if it's an easily teasable name, we don't want it. What do you think?
