time.
2. Their parents wants them can speak foreign language, especially English.
3. Their baby cannot speak or walk as fast as usual baby.
4. Before the baby study in kindergarden, them must be tested.
For that reason many parents sent their baby to school.The lesson for baby is not same as elementary or kindergarden student.In there the baby was tought how to walk, how to speak English, how to go to bathroom alone, and etc.And in there the baby only having fun, not study for a score like us do usually.
