i don't think 5-6 years is such a big age gap. My kids have 5 years between them and they play along just fine.

I have 10 years between my brother and me. He is older. 10 years is too much as we have nothing in common. We never even fought as kids, he got married real young at 22 whilst i was 12, so i was like an only child.

5-6 years is nothing.

GL with your studies.
