I've been keeping his humidity around 55-62% pretty consistently since he was a baby, now for the past couple months it's suddenly stuck in the 40s, I'm not sure what I'm doing wrong. I've tried to fix the issue with aluminum tape, but it doesn't get any higher than 43%. I've been very worried about his health, I do not want him to get an RI. I've always misted the corners, which I also recently learned isn't great, so I started a method I read that said to wet the bedding with a cup of water, mix it in, and then add a second layer, that didn't seem to work either. However, I don't have a humidity gun I can put over the bedding, so it's possible I may not be getting an accurate reading.
