I hold Scout probably over 4 hours a day! XD If not more. I love holding him at night and then he falls asleep on me(like he's doing now)...
And I hold our other dragon Riza, whom we've had for only a few days, maybe once a day for fifteen minutes or so, since my sister(who is her other owner, mostly in charge of cuddles and baths, while I work with the feeding. XD)
When she's not brumating, I'll hold mine whenever I'm sitting around at the computer, or just watchin tv or something, so she's out a lot. Now though, I get her out if she's awake... so maybe a couple hours a week?
I usually hold Scarlett as much as possible but make sure that I let her bask before and after she eats for at least an hour or so before I mess with her..
I used to hold Tiamat a lot, but since the weather got reall cold, our house gets really cold. So I don't hold him as much unless it's in front of the fireplace. Which he loves watching anyway, so it works out.
I don't get to hold Sarth while he's awake much during the weekdays because of work - usually by the time I've fed him his dinner and let him bask/digest, it's almost his bed time, so after maybe 15 mins of holding him he tries to look for a dark place on my desk to sleep
During the weekends though he is out for at least a couple hours a day if not more
It varies depeding on my schedule,when I am home I spend several hours rotating between my 2,bathing feeding and all else aside probably an hour or more at bedtime,but try to spend as much time with them as I can. At least an hour at bed time though.
i'm lucky to work in a great place so when its warm i can bring one of htem to work with me so during the warm months i can spend most of the day with them during winter, buda goes to sleep and my baby is slowing down so i'm pretty sure next winter is going ot be lonely
i shoot for an hour a day for each though to be honest sometimes that doesnt happen
I do give Scout an hour or more(if he's eaten a super) to digest his food afterwards, but being homeschooled and being too young for a job is great so I can spend all the time I want with my dragon when he's not digesting or anything.
