My daughter began to contact early childhood education at home in three months. At that time, she was not good at sitting passively and turning over. Her two little hands are always clenched tightly, never letting go of any stimulation. The doctor said it was a lack of exercise and guidance. Later, after studying and exercising at home for more than two months, my daughter can not only turn over, but also grasp toys and small things flexibly.
