Welcome to the Forum. I'll be happy to comment. Let me first reassure you that you are unlikely to have passed your HPV (wart) to your infant on your hands. There is no good evidence that infection is transmitted in this way.
Now, let's discuss your other questions. Please remember that HV infections are common and present in about 80% adults. That your wart appeared to recur is not unusual and happens about 25% of the time after wart treatment. Your husband has already been exposed to whatever HPV you have and there is no reason to modify your current, ongoing sexual activity because of your HPV. As far as you are concerned, other than getting your wart treated, the only thing you need to do is follow recommendations for routine PAP smears.
For more information on HPV I have attached a link to a prior response that my colleague, Dr. Handsfield made to another client. In addition, I would suggest you look at the ASHA (American Sexual Health Association) web site for more information.
