And do they still use fluoride free? If not, when did you switch? When did your LO master to spit? Tips on teaching my LO how to do this?

My 3.5 year old still doesn't get the concept to spit out the toothpaste, so we are still using fluoride free. We just finished up Tom's brand and then LO picked out one with Paw Patrol on at the store so we are using that currently.
