Not for nothing, and I'm definitely not trying to be rude but this isn't really a stuck in the middle dilema, the only opinions that really matter are yours and his. So as much as it doesn't matter if his family likes it, it doesn't matter if your family hates it. It's just a compromise between the 2 parents.
Why does he get to choose anyways? It should be mutual
To be honest, if it looks hard to pronounce then your child is going to correct people his whole life. I have that issue too. I really like my name but if you can avoid it then try.
Bring it up to your partner! Tell him that you think most people won't know how to say it so your son will have to constantly correct people
If it is a name that is hard to pronounce from looking at it, that is a good enough reason to re-think it. Having a difficult name is hard for children when they are in elementary school and middle school, it prompts a lot of teasing and also if they have to explain to an adult what their name is, it embarrasses them.
What's the name? My husband named our daughter, hanna, it wasn't my favorite name but it was the only one I didn't hate that he suggested. The name grew on me and now I can't imagine her being anything other than Hanna Marie.
Tell him u don't agree and that u really want to choose a name with him that u both love. so what if his family likes it, ur the mother and if u don't love it, then u have to speak up.
