My daughter lied to everyone at school and said it was her birthday

Long time lurker of Reddit, this is my first post. This is about my daughter whose 6.I'm at a total loss about what to do. On the way home from her after school program she says she has a confession to make and tells me that she lied in gym class today. She told the teacher it was her birthday so she got to choose who was "it" since this is a special birthday privilege. At first I stumbled over my words because this is an elaborate con she just confessed too. Eventually I tell her lying is wrong and that she will have to wrote her gym teacher a letter explaining it wasn't her birthday and to apologize. And I was emailing her first grade teacher to let her know what happened. Next gym class is Monday, so she has all weekend to write a good note. I think "Good job Mom! Parenting FTW!" This should be a good life lesson, fill her father in on what's going on and call it a day.Until we get home and I open her backpack. There's a crown for a birthday girl who turned 7 today. So I call her over and ask what this crown is for. "It's my crown." She said. I asked her who gave it to her. "My teacher" I was confused. Gym teachers never gave out birthday crowns when I was in school. So I asked if her regular teacher gave her the crown. "Yes" she says.Time stood still. My brain couldn't handle this confession. My 6 year old girl played the long con on everyone at school today into thinking it was her birthday. They even sang to her.Trying to talk to her about why it was wrong to lie didn't seem to be getting anywhere. So I switched ideas and asked if she thought about how her friends would feel if they knew she lied. That got to her and she broke down crying.Her teacher has since replied back saying she appreciated letting her know today was not my daughter's birthday and the apology notes sounded like wonderful ideas.Is the life lesson here of owning up to your lies and making things right enough of a punishment?I should add that we have had a history of lying, sneaking and hiding with her for the past year or so. This is so far the most elaborate lie she's come up with yet.I'm freaking out, I don't know what to do. If I should punish her or put her in therapy. via /r/Parenting https://ift.tt/2OPReah
