They go for simple carbs. I had a health issue a while ago that caused me to vomit multiple times a day to the point that I had around a 3 hour eating window. In order not to lose weight (I was already pretty underweight), I mostly resorted to gorging on a bunch of cookies etc. because protein/fat are slower to digest.  That said, as a woman with a bunch of anxieties around my first pregnancy (and wanting to do the very best for our child) I'm enraged by these women who are licking their fingers on a whole grocery store birthday cake and cheese fries. You wouldn't water plants with coke and you wouldn't feed your dog McDonalds, so why the fuck are you feeding a growing infant IN THE MOST NUTRITIONALLY CRUCIAL PART OF THEIR LIFE this crap?
