This little one is still a baby and needs to eat almost every day. (when healthy)

I also travel a lot and since he normally burrows to the point where only his eyes are above the substrate
I don't think the crickets are a danger to him.

So after he has had his fill 3 to 5 crickets or dubia nymphs I leave 4 to 5 crickets in the enclosure.
for him to snack on at his leisure.

And I keep a small cricket carrier under his enclosure. it has two black tubes that the crickets crawl into
so all my wife has to do before she goes to bed is to grab a tube and shake a few into the enclosure before she
goes to sleep each night and he does the rest.

Now since your little one is not well you will need to keep doing the soaks.
