I don't necessarily agree that dad can just come and take him. Dad currently has no custodial rights and mom did grant (although not legally) temporary custody to you. The only way that dad could just come and take him is if dad convinced the cops to attempt to force you to release the child, and the cops might very well decline to get involved since dad has no custodial rights. They might consider it a civil matter and tell dad to take it to court.
However, if dad files for custody, particularly on an emergency basis, its nearly guaranteed that you would be required to turn the child over to dad. If dad doesn't file on an emergency basis there is a very slight chance you could delay things until mom gets out...but its pretty slight.
