Reptiles (like most animals) sleep when THEY need to - there is no set time. In the wild, they'd eat then rest in short bursts.
About 15 or 18 hours
I think you should buy a tortoise because they are much easier to care for since they dont need to have instant access to a lot of water.
You should sleep 9 hours
if you are a kid you should get 12 hours of sleep
Yes a baby can sleep with a nightlight without awakening. It does, however, depend on how much of a light sleeper the baby is, since all babies are different. But generally, a nightlight should not be a problem as the light is soothing and not blinding like the ceiling lights.
Because they haven't had as much sleep as you have and they need to catch up on their sleep and that is why the older they get the less they sleep beause they are getting caught up.
Newborns spend more time sleeping than awake so they really don't take "naps" they just sleep a lot. You should let your baby sleep as much as he or she wants to.
Baby red-eared sliders sleep as much as possible when they are young. In nature, they prefer to sleep on rocks or floating in shallow water.
Most of the time, baby can't sleep when they have a fever they just always wanted to carry by their parents specially by their mommies.. in that way they can sleep much better even they are sick :)
Their shell (carapace) into which the tortoise withdraws as much as possible.
because he was very much similiar to a tortoise.
they sleep a little then swim a bit then sleep again is the water too deep they do have shallow spots and things to climb on is this just how they are or should they be sleeping through the night?
