You are responsible for your child. You kinda have to be…legally speaking. At least for 18 years or so. You provide them with food, shelter, clothing, etc…the necessities.
You (me too) even pat yourself on the back (post about it on social media / remind them when they’re in trouble) when you’re extra responsible for your child…you provide a nice yard, send them to camp, pay for an amazing experience, buy them the latest electronics, dress them in really nice clothes, etc.
But do you take responsibility for your relationship with your child?
What are you doing to grow the relationship between the two of you?
What conversations are you having to better your relationship with them?
None of the extra stuff lasts. Actually, most of it will be forgotten.
Your relationship (or lack of relationship) with your child will last for decades.
If you don’t take responsibility for the relationship, they won’t. They’re a child.
