I can't answer why you have strong negative feelings about babies and those having them. If you think it's connected to having an emotionally absent mother, that may or may not be the case. Just because one came before the other doesn't mean there's necessarily a cause and effect relationship.
If this is concerning you, though, please discuss it with a therapist. There are many good ones with experience in treating daughters of emotionally absent mothers. You should most definitely do this if you're planning on having children of your own some day.
My mother never dealt with her issues growing up with an alcoholic mom. As a result, my siblings and I have struggled with depression, anxiety, and troubled relationships. I firmly believe that our lives would have been so much better if our mom had just taken the time to work with a therapist before having kids. We need to be healthy, both physically and psychologically, before becoming parents because it's a tough job even for those who are emotionally stable.
It's a wonderful thing to be curious about yourself and wants to learn more about what makes you tick. This is especially true for you since your mom was preoccupied with chasing men during your childhood. Taking a journey of self-discovery is exciting and will enrich your life.
