Please help with SIP of 2LPM allocation and existing fund review

My current funds are:

1. Parag Parik Flexi Cap - roughly 70% current SIP

2. Zerodha largemodcap 250 Index - roughly 30% of current SIP

3. Quant Smallcap ( Stopped New SIP 2 years ago)

4. Motilal Oswal MidCap ( Stopped SIP 2 years ago )

Per month investment: 2 lakh+

Current Age: 33

Time horizon: 20 years +

Risk Tolerance: currently moderate but I would want to be stable in a decade.

Objective: 1. Children fund for marriage plus higher education 2. Retirement

Is this allocation good? Personally, i would be happy with 10-11% return. Not sure if I have selected Good long term funds.
