Thanks guys for worthy feedback. After going through the inputs, I thought I'd go for a digital compact camera on top of my d90. I'm not going to get rid of d90 & spend on a micro third lenses & flash yet again.
So, I'm down to is it RX100 or something else

I recommend keeping your DSLR and get a compact camera like the RX100.
DSLR's great when your kid is still in infant stage or at home.
But when they starts to walk and when you're outside, then the hassle begins.
When my daughter starts learning to walk, she refuses to sit tight in her stroller so imagine this... my wife will be pushing the stroller laden with bags of kids stuff and I'll be chasing after my daughter.
Shooting a dlsr with both hands while crouching down to kid's height with camera bag getting in the way is no fun.... by the time I try to shoot off a photo, your kid either ran off to timbuktu already... or fall down and starts crying
And when you have 2 kids like me........

... DSLR is impossible.
So for me, the RX100 is a godsend.. it's balanced enough for one handed operation and its powerful enough for low light and indoors.
