Don't keep them together...! Could be disastrous.
Once I had an adult living alone and I put a new baby in there with him. The baby was a female and she nagged him to death.Have you experienced any issues by having a baby live inside any if your enclosures with adults?
All new reptiles should be kept in a separate room and never introduced for 30-60 days at all. Also, you must hand wash before handling them to avoid cross contamination, and never wash their food and water bowls together during this time. People have lost their entire collection making this mistake. I know it's cute but they can meet in a month or two when you're sure both are healthy.

Just joking,
But really - why take the chance? Terrible things can and do happen when things go wrong for some reason we cannot foresee.
