My mother in law owns a daycare/preschool out of Mission Hills. If you want more info feel free to let me know
My oldest started TK at 4 1/2. It’s a full time program like regular school. I was so nervous and it was a hard transition at first but I can see a total difference! He’s so social now, so much confidence, learning and making friends. I just made sure to put him in a different school then our homeschool so it’s a lottery and thankfully he got in.
If you can homeschool I think that would ease your mind! If not maybe a bullet proof played book-bag and teach them to use it as a shield. There’s no easy answer, I hate that this is a concern. 🙁
