Dektol is popular, and when you're learning, there's something to be said for that. Given your health/toxicity concerns, though, you might want to consider
As a beginner, should I go with Dektol? Are there any good liquid concentrate developers for beginners? Being pregnant, I'd like to avoid powders as much as possible for the next four months, but I can always have Adam mix it up for me.
As others have said, both gloves and tongs can be useful in this respect. I suppose you could add a lab coat (or dark clothing stand-in), particularly if you're wearing short sleeves.
Also, since I'm pregnant, I'm more worried about exposure. Probably more than I have to be, but I want to be cautious. I'm thinking of having Adam help me by doing the actual developing of the prints with me just standing and watching him. We'll be in a well ventilated area so I'm not worried about that, but getting any chemical on my skin is something I don't want to do.
