have & have had

[Hello World]

Hello,

Have is what I currently have, right?

I have a dog.
I have a cat.
I have a car.

Had is what I have in the past, but no longer have right?

I had baby teeth.
I had baby clothes.
I had gone through pre-school.

I am not sure about have had. It looks like current past. I wonder if you could explain it to me and give me as much examples as possible, so I don't just only use have and had.

Have had- this is the bridge between the past and the present:
I've had this car for two years = I bought it two years ago and still own it today.

But What is the meaing of had here

It is not 'had' alone, but 'have had' and it means that the ownership is both past and present.

Thanks. I got it.
