There is no restriction of maximum number of children you can mentor. However, this is a long-term commitment and involves monetary contribution. It is completely up to you how much you will spend for a child. You can set an annual limit as well. It primarily depends on factors like age, gender, location etc. Based on our experience, it varies from INR 1,250 to 5,000 (USD 20-80) per month for a child. On an average, we consider INR 2,500 (USD 40) per month per child.
