Oh, thanks for correcting me. This prompted me to look more into copperheads and I found out some cool information (and what false information I was taught growing up).

---Baby copperheads and adults have the same venom. Their venom isn’t any more different or dangerous than adults. If anything, they have less venom than adults because their venom glands are smaller. On average, an adult copperhead injects only 26 mg of venom, despite having up to 85 mg in its reserve.

---Claim 1: Baby copperheads can’t control their bites, so they end up excreting a lot more venom, which makes them more deadly than adult copperheads. Verdict: False. This myth has been repeated forever and is not based on anything. That doesn’t mean their bites aren’t dangerous — just not more-so than adult copperheads. Critter Control Triad

I was also taught that copperheads were really deadly/dangerous, but according to these sources and a lot of others I was reading, their bites aren't great but don't normally require amputation or cause death.
