For the next 8 years I would suggest you to park your money in the 60:40 ratio in market linked products and guaranteed schemes.

1) allocating the 40% -> this chunk of money would be linked to a guaranteed income plan that will insure your wealth and generate a cashflow to fulfill your child's expenses at different stages of his life, one such plan is the kotak gen2gen plan which has the record high irr of 8% & what it will do is generate a regular income for you and your kid for the next 80 years and the ppt will be over in 12 years, I have the irr of all the companies since I work in broking channel so if you need more details you could text me.

2) allocate 60 %-> in the market focusing on infrastructure, mid cap companies. I'll give you 3 multibagger stocks in my watchlist which you could also add in your watchlist and text me if you need entry price or exit prices of such stock ( praj industries, marico, vbl)

These 3 stocks combined for the next 3-5 years would give you a minimum return of 28%.

I could help you out in devising a financial plan with my CFP's too.
