7 month old refusing bottle and breast.

Hannah • Hey my name is Hannah. I am a 27 yo SAHM 💙👶🏻 💙4/29/16 💙👶🏻 💙4/23/18
My son is EBF. When he was 5 months old he started getting 1 bottle a day. He refused the bottle until that point. I have a very good supply built up and it is stored in a deep freezer that is never opened. This past week he keeps turning away from my breast and the bottle no matter how fresh it is. Is this normal? Is there anything I can do?
