DD just turned 4. I have been taking her to a children's gym for a whole term, where I stayed with her during class. Based on the instructor's advice, I have enrolled her in parent free classes for the next term, but she has point blank refused to go without me. She is usually quite confident without me, and goes to nursery everyday, no issues. From bitter experience in the past, I know that if she has made up her mind, little can sway her - even chocolate doesn't work as a bribe. What can I do?
