In my experience, they only need care once a week to once a month, so that can be good or bad. Great because they’re not a lot of work, but can be bad if your child needs tasks to be daily to remember them.

They don’t bite, and after a while you will have a LOT of them, so if your child accidentally handles one too roughly and it dies, it becomes more of a learning experience than a tragedy (I say as someone who killed two goldfish as a toddler and am still haunted by that).

I recomend zebra isopods or dairy cows or another “great for beginners” species. Don’t start off with an expensive species first. Zebras hang out in the open, and dairy cows are super easy to care for and get fairly large. There are a ton of great YouTube videos on keeping isopods out there, especially beginners.
