Everyone hates what I'm naming my son..

So my husband is the 3rd and I call him Charlie. His dad is called Charles. Since our son is going to be the 4th I didnt want to call him Charles or Charlie, so my husband and I decided on Chaz.

Well, everyone hates it and is being super vocal about it and its really hurting my feeling :( Mainly it's his family and friends. My family loves it! I feel they should be happy I am even following their family traditions because if I had it my way I would have chosen a completely different name!

I know I should ignore it but they say they arent calling him Chaz they're calling him Little Charlie!! My husband and I dont want that because Charlie is my husband and we dont want Chaz to get confused. We told them that and they said they can call him whatever nickname they want :/ I just wish people would shut up and keep there opinion to themself, this is our son and we have the right to name him whatever we please.
