Weaning 16 months old

Now that my son has a full mouth of teeth breastfeeding is getting sooo uncomfortable on top of that he keeps biting me πŸ€¦πŸΎβ€β™€οΈ when he’s in daycare he drinks cow milk from a cup. However when he’s with me he cry’s to nurse. He now started waking up through the night to nurse repeatedly. I would like advice on how i can completely wean him from nursing
