New baby

I'm currently 5 weeks pregnant and have an almost 11 month old (on the 20th)

He is still breastfeeding and sleeps in the bed with us. I wanted to continue breastfeeding until the new baby gets here but he recently started biting. Nothing I do will get him to stop, he thinks it's funny. I'm wanting to wean once he turns a year, since he sleeps with us in the bed he feeds every 2-3 hours at night. My plan is to stop the feedings and then try to get him in his own bed. Does anyone have any advice or tips? TIA
