Personally, I don't think colds n such can be passed from human to glider....but I'm not a vet
About a month ago I had a severe head cold, fever etc... I left my pair in the cage for about 2 days, when I could sit up on day 3 I had them out and in my sweatshirt. My cold held on for about a week and a half and I had my gliders out and on me for all but the first 2 days. They were just fine, and still are... honestly they made me feel better a lot sooner lol. I think they Knew I wasn't feeling well and not at 100%. Both of my gliders were more mellow than usual and just wanted snuggled. Soon as I felt better they went back to their normal "don't snuggle me!" selves
Congrats on your new babies and I hope your kid feels better soon
