My 5 1/2 year old just recently started really trying to avoid his teeth being brushed at night.

I feel like I’ve tried many ways to make it easier, but to no avail. Letting him brush part time, preparing for it, reading books about it, etc. He still almost panicked every time. His main reason for not wanting to brush his teeth is because he’s hungry… and I have tried at feeding him larger meals during the day and offering a snack a half an hour before bedtime. Any advice?? I’m struggling 😩 I’m tired of fighting every night.
