Yes, having piano at home is a must condition to start piano lessons.
Acoustic piano is always preferable, it will help to develop proper piano techniques. However it is acceptable to use a digital piano with touch-sensitive and weighted keys in the beginning of the learning process.
The maturity level of young children varies greatly. If your child shows an interest in learning to play piano, if his attention span long enough to practice 10 minutes at home, if he is able to sit still for 30 minutes during the lesson and follow the directions, I would recommend to give it a try.
I require my students to practice daily, however practice time depends on the student’s level.
If your child is thinking about quitting piano lessons, I would appreciate if you could share with me as soon as possible.
Do not hesitate to ask me, and I will happily help you.
My students purchased the bench in the link below and were pleased with this item:
