Toothpaste for a 2 yr old?

My toddler first of all HATESSS brushing his teeth! I literally have to hold him down and I feel soo badd :(

Now toothpaste… is it safe to use a tinyyyy amount of FLUORIDE FREE toothpaste for a 2 year old? This is the one I have, it even says safe to swallow..

I just KNOW my son will swallow it lol and doesnt know how to spit it out yet!

Wondering what other 2 year old moms are doing! Some dentists telll me just water is fine, others say toothpaste is fine too!

Do you brush day and night like an adult with a tiny bit of toothpaste orr?
