I have a ppf account and this will be the 7th year of my PPF.

I have suggested many people(collegues) to open PPF for saving in 80C.But mostly 80% times my colleagues aren’t interested because of long period of 15 years.Now this lead to me to a different question same will come true for my children in future(presently i am unmarried).

So a doubt has arise in my mind.I know a person can deposit at max 1 lakh in his own and kids account.So suppose as soon as i have a kid i open a PPF account for him/her and deposit say 30K yearly to his/her account(70k In mine as ill have more compounding power).That way until he/she turns 15 or say 16 years they doesnt have to worry about a long lock in and has to worry only about renewing it after every 5 years till they need it.Is such practice allowed? Or after 18 years again a 15 years set in?
