Let me tell you real practical answer in this regard with reference to this particular question.
The child may be just 5 or 6, I presume. As such there cannot be any account which can be opened on the name of the child. There is no question of the child operating the account at all.
What can be done is you, as father and natural guardian can open a "Minor account operated by Father and Natural Guardian" in the bank. Though the data could be filled online, for KYC verification you may have to personally visit the branch where you are opening the account . As you are already account holder of the bank, your customer ID is available with the bank. You may have to submit the copy of birth certificate to show DOB of the child and if needed the letter from the school asking for opening such an account.
If it has to be necessarily a joint account in the name of child and yourself, then the name title has to show that(Name of the child -minor, by F&G..)- and your name.
The account can be continued and when the child attains age of independent operation (10 yrs ) and able to sign consistently, the account can be converted to child's name alone if you want like that.
Generally in Minor accounts, there will be some restrictions and thresholds in transactions.
