Awww, I can tell you love your DD very much

It is very normal to feel a little sad though, I felt the same way when DS1 started 3 year old kinder. And then the first day I took him to 4 year old kinder this year I nearly teared up as I drove away! He was so happy to go and it made me feel a bit sad that he doesn't depend on me as much these days. But by the second day I was actually really happy and so proud of him.

You are obviously doing a fantastic job with your DD if she went off for her first day so happily and had a great time. You are teaching her to trust others and become independent, what a great gift

Soon you will start to relax and enjoy your little bit of time to yourself. Make sure you do something really relaxing
