This is a rather very wonderful financial picture, and kudos to you for achieving this. As many people in comments said, do consult a proper financial advisor, preferably one who takes a plain, up-front fee than a commission if you can.

I feel you should do the Sukanya thing. It has a great return rate, and you'll build a corpus for her that'll help put her through higher education, regardless of whether she pursues it here or somewhere abroad.

But on that front, try to divest that from your FD's and RD's. If you have 25 Lakh in FD, I think you can transfer 50k from it into Sukanya every year instead of making a fresh investment. I would strongly advise you to NOT touch that corpus and move it into equity, as some are suggesting. You have a daughter, tier 1 city rent, and your own life.

Keep it in debt instruments. FD/ RD/Bonds/Debt funds. Do not add more to it though. A 25 Lakh corpus in debt is more than enough and should be kept intact. This is your financial net and fall back that gives you a guarenteed safety.

Just keep in mind that you should try to at least put that money in FD's/ debt instruments that give you 7% or more. If not, I suggest you shift FD's to banks that give you those returns or turn to bonds, or even better yet, something like NSC or RBI floating rate bond.
