I don't know, I formula fed. I didn't smoke or vape while pregnant, though. I would have a couple of sips of beer from time to time while pregnant, though. Parenting has gotten to be something that everyone, especially people without kids, like to judge about. When I was pregnant I had people judging me for eating deli meat. A woman from an online parenting group called child protective services on me because I began sleep training when my son was a few months old (allowing the baby to cry for brief periods of time between comforting at night, to encourage them to self-soothe and learn to go to sleep on their own). Ironically, the cop that came out thought the whole thing was insane and she was in the process of sleep-training her son. It's gotten ridiculous.
