I never have feed a baby something that they shouldn’t have but I know of an instance where someone did…
A neighbor of Mine was babysitting for her granddaugther. The mother had placed a water bottle filled with VODKA in the refrigerator. The grandmother used that VODKA to fill the bottle with the powder added.
At some point after the baby wouldn’t drink the bottle (because of the taste I imagine) but had drank some the Grandmother realized it was Vodka instead of WATER. She gave the baby Powdered Charcoal and the baby vomited the milk mix up. The baby was Ok and no harm done.
She was lucky to have the powdered charcoal around. It is hard to find now in the stores. When I was a child (50’s-60) it was common for All medicine chests to be supplied with Charcoal. I still keep some of that in My medicine chest. I live in a rural area. It would take me 45 minutes to get to a Medical facility. An ambulance takes 14 minutes to get to my house and 45 minutes to get to a hospital.
Now I can say that I have feed babies things that are not recommended at their age. For example, If a baby is not getting full feeling off of just formula, I would make rice cereal and feed the baby that. Some babies are just to big to be satisfied on just milk. Rice is a good filler and does No harm. (like I would not use wheat cereal)
I also would give a baby warm tea when they had a stomach ache. Tea of course has caffeine in it. That would not be considered kosher. I also feed My grand daughters sweet tea. They love it. it is better than many sugary corn syrup infested drinks other chose for their children. I use 3/4 cup of sugar for every 2 gallons, so it is NOT much sugar.
