I’m so exhausted. Can someone please help me?

Im a single mom and have been trying to get my almost 2.5 yr old to brush his teeth but he HATESS it with a passion. Ive been trying for awhile now!

I do blame myself alot for not starting much earlier. I really should have, I know, I get it, pls no shaming here.😞

Ive done songs, “oh no bugs in your teeth!”, brushing together, electric toothbrush etc and he still screams and says NOOOOOOO!

I usually have to hold him down and do it which he screams and fights me for too.

How can I get him to do it on his own?!?

The amount of guilt I feel is so immense that I took the day off work today because I am mentally EXHAUSTED from trying to find a way. Please help!
