My parents were old time hunters and trappers who were born in the wilderness ... so they weren't up to date with the latest pediatric recommendations at the time.

Babies can't process caffeine in the same way as adults. If anyone is reading this and thinks it's a good idea to give your child black tea of any sort, you should absolutely wait until the kid is at least 10-12 yrs old... The kiddo will be absolutely wired and it negatively impacts their ability to sleep. Overall this is a very bad idea.

Edit: also refined sugar is a big no no for kids younger than 2 yrs old.
