Leopard geckos are great. Super docile. Buuuut most geckos aren’t great for young kids if you plan to handle them. They’ll drop their tails if grasped. Also nocturnal, so will mostly sleep during the day.How were the leopard geckos? I haven’t done much of any research yet but my kids are really into them.
Bearded dragon is probably a better “handling” lizard for kids and diurnal, so more interring for the kiddies.
