The transfer factor oral liquid produced by Changchun Jingyu Pharmaceutical Co., Ltd. is definitely no problem for children to take, because our family is a children's specialized hospital and this is what we use. As for the instructions, I'm sorry I didn't read them carefully. If necessary, I can attach a copy to you.
Product specification: 10ml*6 pieces, children 1 piece every other day. About 30 yuan is less than a box.
