Getting ready for school

I'm planning to put my daughter into school, too. She'll be 2 years and 9 months when the schoolyear starts. Some say it's too early and she might get tired of school at such a young age and has advised me to wait until she's 5. I think otherwise. I see in my daughter the eagerness to learn. I think putting her into school this early will also give her the chance to play and interact with more kids her age.
