I'm still a newbie here myself, but I agree - plan on short periods of handling time, especially at first. I make an attempt to handle each of ours daily (as long as they haven't eaten in a few days and aren't in the blue). If I see their heads poking out of a hiding spot or they are roaming the viv, I will usually just talk to them and slowly put my hand near them so they will know it's me. I have two that will crawl right onto my hand most of the time. Since they like to just 'hang out', I keep those two out until a little longer - about 30 minutes or until they start seeming restless.
The other two are still adjusting to their new homes, so I only take them out if they are already roaming their vivs, and only for a few minutes. There are times when I've just picked them up for 5 seconds and then put them back down. The littlest one we have used to fidget the second I picked her up, but she seems to be getting used to it now. Each time she seems less nervous and more curious, and the handling lasts just a little longer. They just need time to realize you are not going to hurt them. Some seem to figure it out quickly while others take longer, or simply don't want to be held no matter what. They all really do have their own personalities
Also, I have a few old soft fleece ankle socks that have no match, so I trimmed any loose threads in them, and started using them as little pouches for our corns to go into when they are out of their vivs. It's a portable cozy hide

I keep one nearby any time I have one of our kids out. If they seem nervous, I hold open the sock and they crawl right in. They will usually keep poking their heads out to see what is going on, but they definitely feel more secure having a cozy place to hide in when they need to. My amel, Arya, has actually fallen asleep inside her sock with me holding her
Congrats on your new scalebaby! ^_^
