I want time to stop

You know growing up I couldn't wait to hit 12 and after 12 was 16, then 18. I am sure my kids feel the same way and while I spend a lot of time wishing they would just grow up, ( I am getting much better at trying to let them just be kids and make sure that we daily spend time outside together as a family making memories) right now I just want time to slow down. My kids are growing up too fast. It wont be much longer that I will be able to get them to play in a pool like this in our front yard. They already try to run from my good bye kiss in the morning after I walk them to school. I guess soon they wont let me do that anymore either. Can't time just slow down for a bit? I'm not ready for my kids to grow up!!!!
