There have been studies about this, and from what I have read, the impacts to the fetus are only in extreme cases like the Irish famine or the Holocaust.

I believe genetics is almost solely responsible for temperament. Womb conditions don’t effect temperament.

Not true for me. My most athletic and active son was the most laid back in the womb - to the point of me worrying! He was also the biggest so maybe he just didn’t have enough room.

I had an extremely stressful second pregnancy. DH went off the rails and I handled it poorly. We ended up separating for a few months. Then, black mold was discovered in our apartment and my older child and I had to move to a hotel. I had no idea where we were going to go when I left the hospital with my new baby.

She is an easy-going, chill and happy two-year-old now!

I believe most of it begins even before your child gets to the womb...while it’s still traveling down the Fallopian tube .
There have been a number of studies on this with identical twins (same DNA) who grew up in different families through adoption. Temperament is largely genetic.

No, it’s about 80% genetic and 20% upbringing/early life.

I was very anxious with my first. This child is fearless. I wouldn't call him chill, but he's never been a worrier. He is "passionate" though. In many ways he is a perfect combination of my dad (gets very into things) and my husband's brother (reckless and happy). Nothing of me or my anxiety ridden pregnancy in him.

I've been pregnant under stressful conditions twice and the two kids are nothing alike! One is high-energy and needs. The other is super chill.

Yes but because of genetics not a chill mommy.

I had a very chill pregnancy and have a very intense kid. Genetics and nurture matter, pregnancy conditions not so much.

An anecdotal sample from my friends - those of us with active babies in utero had active kids, and the quiet ones stayed quiet.

Yes I believe temperament is largely genetic and my kids emerged with distinct temperaments that have been consistent from the get go. However my low key kid gestated during the hardest period in my life, my more difficult child during an easier time so at least in my case there was no correlation between my experiences and their temperaments.

I had a very stressful, unplanned pregnancy. It was an easy pregnancy (no morning sickness or other issues). My DS has ADHD and he would have it even if I had an easy pregnancy. It's genetic.

I am one of the many women who found out they were expecting right at the start of the pandemic. It was scary and filled with mixed-emotions. I understand no amount of prenatal anxiety is healthy, but for seasoned moms, curious to hear antidotes on your child's temperament regarding your pregnancy.
