My lo hated baths as a newborn and would scream the whole time, then when he was around your lo's age he would stand them a lot better and seemed indifferent about it all. I think around the 3month mark I started giving him a bath nightly as I wanted it to be part of his nightly routine. He now LOVES his baths and squeals and splashes around, a total turnaround. He's never in there more than 10mins as they can get chilly very quick, he made the move to the big bath as his baby one got small very quickly. We got one of those support holder things which is great as it frees up your hands.
