Cat owners! Please help! I'm clueless

Me and my husband recently took in a male kitten. At his home before us he was thrown outside at night, carried around by his ears, and barley had any human interaction. I feel horrible for him. We named him Milo, bought everything a kitten would need and want. And we have been giving him love ever since. Well he has a huge biting problem, I don't think he wants to hurt us, I think he thinks he's playing. I will be sleeping and wake up to him bitting me to the point where he drawls blood. Me and my husband hands are full of bites and scratches. I'm 35 weeks pregnant with our first. And I don't want him hurting the baby. It's also not in my heart to get rid of him. I don't want him to feel unwanted like the previous owners showed. I tried getting chew toys to replace my hands and that didn't work. Will neutering him, help him calm down? I'm desperate for help.
