Such a bad mom

I have to post about one of my not so proud mom moments. Yesterday a couple of friends and I decided to take the kids to the park. The weather was perfect. So nice that we ended up staying there for 3 hours. It was really fun. At least until it was time to go home.
I put Anni in the car and threw the keys on the front seat. I then picked up Max and threw him in and shut the driver side door. Max started going crazy and really wanted out. Anni's door was still open until Sophie decided she was going to help out mom and shut it. I immediately tried to reopen it think nothing of it until I realized it was locked along with all the other doors. I then started to panic. I started digging in my diaper bag to find my cell phone but it wasn't there. Not to worry it was safe in my purse inside the locked car. Then panic really set in. I saw a lady over on the park equipment playing with her cell phone so I decided to run over and ask her if I could use her phone to call Shawn. Of course her cell phone was dead. I then asked her if you would mind watching my car why I ran over to my in laws house to use their phone. The lady was really nice and agreed. On a dead sprint I ran over to my inlaws and called Shawn. Just as I got Shawn on the phone Jay, Shawn's dad, drove up. I hung up with Shawn and quickly explained to Jay what happened. He told me to jump in his truck go home and get the some more keys and he would go over to the park and watch Anni. I drove as fast as I could to get home and back to the park of course not without hitting every red light. When I got to the park and unlocked the door Anni was screaming her head off. I felt SO bad. I was so upset and felt like the worst mom in the world. I am still not sure how the doors locked. The only thing I can think is that when max was freaking out in the car he stepped on the lock button. Lesson learned the hard way.
