Bless you!
Personally I agree with the majority of the berries you should have a say in what you name your child. I actually think you should have more of a say as your the one enduring pregnancy, labour and postpartum period. Furthermore as we know being a mother normally makes you the default parent so you’ll be doing most of the legwork throughout their lives so yes you should have a say and you should assert yourself early on by establishing that you want a say with this baby’s name. Also future generations will be grateful that you’ve smashed this patriarchal tradition by not having a IV. I haven’t endured this but my mother did. My dad’s family had the tradition of boys being named Robert John, next generation John Robert, next generation Robert John in this pattern since as far as he could trace his family tree but my mum refused to follow this pattern. She said it was her son and she would name him what she wanted so they went with William Leonardo John (Leonardo is a family name from my mums side) and I’m so grateful she did break this tradition as
me and my siblings have naming freedom! We are not governed by patriarchal expectations surrounding legacy. I strongly recommend breaking this legacy but that’s just my feminist thought process.
Furthermore his legacy is being passed down through DNA and his surname. How much more of a legacy does he require to be passed down? Also has he stopped to consider that you are also an individual therefore has familial history aka a legacy that you can also bestow in whatever shape or form onto your child? This whole thing feels so him and his family focused. As @SparkleNinja18 said this gives narcissistic vibes it’s just not the best.
Anyways moving away from my feminist smash the
patriarchy thoughts and onto solutions I would follow @EagleEyes idea of having two middle names consisting of this legacy name. As they explained and I’m reiterating have for example the legacy name of for example Thomas John in the middle spot with your name upfront. For example Isaac Thomas John Cunningham then you’ve passed on this legacy name with Thomas John but you’ve also been included with Isaac. Furthermore this prevents any confusion of having two Thomas John’s within the house and in the future referring to your forty year old son as little Thomas which isn’t the best and I see in so many ‘legacy’ households.
Stay strong mama
