Hey ladies, i really don't know what to do. I'm heart broken. 😭 My son refuses to nurse.

Today i noticed a tooth making is way out. He started being fussy & everytime i tried to nurse him he'd cry so loud. I tried for 1 hour & nothing. I gave up & told my husband to get me a bottle & i gave him 8 Oz's of formula. He didn't even hesitate. Could it be he doesn't want my boobs anymore? 🙁 I've always said i wanted to stop breastfeeding at 6 months , but now that he refuses the boob , it actually hurts. 🤦🏻‍♀️😔
