Playing with kids

I’ve posted about this before but it’s bothering me again. I’m a mom to a 6 year old boy and I suck at playing toys with him and I feel horrible about it, I try to sit on the ground and play cars or play bluey and just follow his lead but I’m still not great at it. Does this make me a bad mom? We do other things together like reading, coloring, going to the library, going to fun places when he doesn’t have school. My husband is great at playing hot wheels and monster trucks with him and I wish I could play the way he does 😭 anyone else struggle with this? I know he’s only going to be little once and I want to enjoy the time while it’s here.
