PLEASE HELP! Not eating due to teething.

Experienced mommy's please help. My son was the best eater he ate every two hours on the dot 4-6 oz. He was in the 90% percentile. As of this week he is refusing to take the bottle. He is eating half of what he used to. I am so worried.

I feel like he has to be hungry but his teeth or itching isnt letting him. I saw my niece dwindle down to being tiny from a stomach virus so I am completely traumatized with babies losing weight.

What can I do to make him eat? To make his appetite come back? I have yet to buy any of the oral gels but I do want to. He has teething toys but he doesnt have complete hand mouth coordination yet. He chews on his hands more than anything .

Please help. Any tips or just your experiences would be so greatly appreciated. I'm stressing 😫

Btw he is shy of his 4 months and no actual teeth yet.
