Hi, welcome to the forum! Your babies are very cute!
Just a few things I thought I might mention. They don't live together, do they? And, I'm sure you've heard it before, just want to warn you about your substrates. Both sand and pellets are classified as loose substrates, and while this is debatable, there is no question about the fact that loose substrates can cause impaction, so many, along with me, believe it should be avoided. I mean, why put you pets at risk when you don't have to? Better choices would be any sort of solid substrate, such as: tiles, non adhesive shelf liners, basically anything that is solid, and easy to clean.
Wish you all the best with your babies, let us know how you go! Feel free to ask lots of questions, and more photos are always welcome!
