Best way to brush baby’s teeth?

My baby is 1. She has 8 teeth at the moment. I’ve noticed a faint yellowish hue towards the top of one of her teeth (near the gums). With everything going on right now, I don’t want to take her to a dentist unless absolutely necessary.

We brush once a day (at night before bed), but I’m going to increase this to 3 times. We usually just give her a brush and she chews on it and likes using it, but I don’t think it’s actually getting the job done.

I’ve ordered finger brushes now so we can do it ourselves. Do you think that will work? Do you have any other advice?

This is a baby who will squirm and cry/keep her mouth closed - every time we have tried to brush her teeth before. So I know this is going to be an ordeal.
