We were having the same dilemma! It drove me to take a parenting class, which helped in many areas. The bottom line is that my daughter just did not want to go to school. We talked and there didn't seem to be any problems at school, she just had more fun at home with me. That said, my parenting class helped me with a plan.
I bought an inexpensive clock and popped the clear plastic cover off the front. I put a heart and diamond sticker by the hour and minute of the time we would be walking out the door for school. Then I put the same stickers on the corresponding hands of the clock. I snapped the plastic cover back on and hung it next to her closet in her room.
I talked with her teacher ahead of time and told her about "the plan." She said she had three students with the same problem the year before, and she was happy to work with me.
I took my daughter aside that night and told her I loved her too much to nag her and fight with her in the morning. We were all tired of that - we agreed. I told her we would be walking out the door in time to get to school on schedule. If she wasn't ready on time, I would put the remaining items in a bag and she would have to dress at school.
I was a nervous wreck. My daughter sat on her bed playing with her cats - in her underwear. When it was time to go, I wrapped a blanket around her and sobbing, she walked barefoot out to the car. There was lots of drama, and it took everything I could muster to follow through.
Being a strong willed child, she tested me another two days, and I just bagged her clothes up and took her to school. I genuinely sympathized a lot with her about the sad situation she had put herself in.
This became her problem to deal with not mine.
Now, we have NO problems getting ready to go. She later decided to put her clothes on the night before so she can watch a few minutes of cartoons in the morning. I thought that was a good solution, so I let her.
About eating, I tell her, "I will be cleaning up breakfast in 10 minutes. I hope you have eaten enough to last you until lunch time." Then, I follow through.
