I totally feel you, mama!
Being a half Asian, half Caucasian, my son is on the short/small side, he is small and he was born premature to top that, so he still has a lot to catch up. He is 8 and thriving in health wise. But since he is small, he has been bullied since preschool again, I kid you not. We sent him to taekwondo and then jiu jitsu classes. Didnt seem to help his confidence. He is still not able to stand up for himself. The mama bear in me always wished I had super power of some sorts to protect him. Sometimes school just cannot help, and yes there is just little police can do when its that young of age. Talking to the parent(s) also sometimes dont help, its annoying, so I totally understand your rant.
Sending hugs!
Oh my word shame @thekitchenfairy. My heart aches for what you must be going through. Not nice at all and I can totally relate to the super power thing. So sad that kids have to go through these types of things. Thank you so much for sharing with me, I really appreciate it :)
