Can you give your HPV to a baby by taking a bath with him?

Why risk it? There is no cure for hpv. It can be transmitted by skin to skin contact so why risk it, even if risk might be low. Hope you are having regular pap smears done.
HPV baby transmit. There have been cases where hpv has been shown to be transmitted from a parent to a child: during birth (with babies occasionally infected on the vocal cords), babies and moms sleeping together, and, yes, probably in bathing together as well. The prevalence of hpv being as high as it is and the scarcity of cases of such transmissions being so low, you should consider the risk minimal. No worries!
