Help please

My breastfed baby is on a nursing strike it is day 5 and he has no interest I can’t get him to patch for more than 3 seconds then he screams and pushes my breast away. I’ve tried skin to skin. Warm bath with baby. No shirt on for a day so he can see them. I’ve tried hand expressing milk into his mouth he pushes it away I’ve tried everything he just up and stopped nursing all the sudden and I’m so emotional I’m not ready for him to stop. I need advice or helpful tips please

He is 10 months old we have had a fantastic breastfeeding relationships no hiccups up until 5 days ago. He is not starving I am giving him pumped breast milk in a bottle he’s being taken care of I just want tips to try and get him back to the breast from the nursing strike.

UPDATE: HE DID IT!!! day 8 and he’s nursing like a champ!! I’m so excited thank you everyone for your tips and responses! It was his teeth they popped through his gums and he didn’t want a bottle anymore.
