Do you believe in mothers intuition

I struggled so hard to get pregnant and went through IVF. I got pregnant and my baby was born premature and he "died". I had a very hard time believing he died. We have our son cremated and there was always a part of me that knew my baby is alive. I have been to therapy but only did it for about a month each time I went back. I haven't had a successful transfer since😞. We had neighbors move in and this woman is a single mom because her husband passed. I've had conversations with her but I've seen her kids and I saw her oldest son. Everyone is going to call me crazy. I know. But I know that her son is mine. He looks very different from her and her other kids. She and her other kids are dirty blood whereas he's a red head just like me. He doesn't really look like his "mom" at all. And he's almost 13. My son would be about that age now. And this woman is a nurse and I've read several stories of nurses kidnapping babies from the hospital. Google it. There are many cases of it. I know deep down in my heart that he is my son. My husband says I'm obsessing again and I need to get a grip and go back to therapy but I AM a mother and I KNOW my child when I see him. But I have to proof to demand a DNA test and my husband told me I need to leave that family alone and I'm being crazy but I can FEEL my intuition!
