Indecision about having kids - Any advice?

Hi everyone, I need some advice on how I can resolve my constant indecision about having kids. In my 20s, I had a strong desire for children, but now in my mid-30s, I'm not sure anymore. My feelings fluctuate - sometimes I really want a child, but that desire quickly fades when I consider how much energy it requires.

My partner is in the same boat, making it hard for us to reach a firm decision. I thought taking it one step at a time might help, so I started doing some prep work like talking to my doctor and taking prenatal vitamins. But then I find myself questioning what am I doing.

We recently got a puppy after two years of postponing, and we're doing remarkably well with training, caring for, and meeting her needs. Sometimes I wonder if our fence-sitting about kids might resolve itself similarly - that once we take the plunge, we'll rise to the occasion.

But I can't help but torture myself over this decision. Why am I unable to make up my mind on something so significant? This has been consuming my thoughts for the past two months. I went to therapy and initially decided to move forward with having a child, but now I'm backtracking again.

I'm also scared about the lack of family support. We would have to do everything ourselves, from childcare to household responsibilities. It feels overwhelming.

I'm struggling with this constant indecision and could really use some advice on how to gain clarity and confidence in whichever path I ultimately choose. (Don't suggest therapy please. )
