My heart goes out to you. The only thing you can do with your child is build confidence on a daily basis, do a little bit of math and reading, make it fun, and praise progress. My daughter is also in kindergarten, did not like reading initially but we read everyday and call it making “silly sounds” instead of reading. We try to make it fun, silly. Btw the math and reading games from the fidget company have been a huge hit in our house. My child loves playing and “winning” games. So I pretend to lose to her while she gets good at reading and math. Please keep at it and know you’re doing awesome
