I found a small note in DD aged 8 in her school coat. It says on one side “I hate your glasses” and on other side “dumb” with a picture of DD’s glasses. She’s in grandmas home right now (MIL) but I texted DH (also at MIL) and he thinks I should speak to school on Monday but I think we should show the note to DD when they come back and ask her what it’s about. DH is texting me saying I’m stupid and have no idea how to talk to kids and I will just push her away from us. What should I do please? She’s our eldest so this is new territory for us.
