Hi, have you read Tom's threads on sulcata care? It's more important that you keep his hide warm and humid. The substrate inside his hide should be moist but it also needs to be about 95 degrees. The ambient temp should never go below 80 degrees. Do you have a fogger or humidifier for his enclosure? if not, it's going to be difficult to keep the 80% humidity level you need. Spraying often can be done but you'll have to spray several times a day while maintaining warm temps. What does his enclosure look like? Are you using a lid? Can you post a pic of it and your baby?
