I am mum to 2 sons-age 9 and 7. We’re very close. They both think I am amazing (even though I’m far from perfect!) and we have a great bond. I feel very lucky

But…I’m also a worrier! I was really close to my mum at their age (she was single parent and I was only child). But when I hit difficult teenage years, we grew apart. Lots of arguments and no apologies (on both sides). I also can see from friends and family that many of the adult men in particular have difficult relationships with their mothers (my DH is one of those men!).
So, for those of you who have a good relationship and bond with your adult sons, do you think this was because of something you did/didn’t do when they were children/teenagers/adults and what was it? Hoping for some words of wisdom as I would like to do whatever I can to keep the close bond we have and don’t want my children to have the same experience that DH and I had with our mothers!
