Judging from my child's two-year experience in learning small steps, I personally think that the small step course is quite reliable. Xiao Bu advocates that children's early education should return to the family, that is, parents should be their first teachers. I also agree with this view, so I chose Xiao Bu. Do all kinds of study AIDS with daily necessities at home every day and play with children. In this process, my children's practical ability and logical thinking ability have been improved rapidly.
