I thought the same as you and delayed having a second kid as a result. Ended up having two more. The second kid was so much different than the first, slept fine, is way more emotionally regulated, etc. I regret my fear based decision making to delay. The third kid is somewhere between the first two. Fear based decisions don’t always lead to the best outcomes, though I am in no way dismissing the fear :)
