I guess I'd expect boys to end up gravitating more to DH as they grow up-
Why?
It’s the same as any friendship/relationship, you need to find common ground. A penis is not it.
Forget the stereotypes and find interests your boys enjoy doing. Don’t assume it will be football and computers, and only “boy” activities you wil hate.
Look beyond gender roles. You may find you adore Lego or Marvel films. They may grow up to love shopping. It’s about finding activities you have in common and enjoying them together, rather than assuming you won’t because of a penis.
I am not a boy but I still gravitated toward my dad as I grew up. He enjoyed Sports and science, and I did too. I actually ended up with a pretty poor relationship with my mum because she felt I should be more like her, be interested in clothes, getting my nails done etc. I simply didn’t enjoy spending time with her wandering round shops, i preferred to go to the park with my dad.
My own children don’t gravitate to one or the other. If they want to go shopping they’ll ask their dad, if they Need help with science or sort the pets they ask me. We all know who likes do what and work on that basis, rather than separating by sex. Which actually I see many parents doing. Boy spends time with dad playing footie, girl is with mum at ballet class, shopping, or getting their nails done.
