Baby's First Foods

Oliver is the following things:

Four months old.
Hungry every hour.
Trying to grab food from my hands/ fork/ plate.
Waking up to eat more during the night.

I honestly wanted to wait until 6 months to start him on solids but he is showing a lot of signs of wanting to start asap! Before I jump into anything, I have some research to do.

Conventional knowledge and recommendations tell us to start with a brown rice baby cereal. Easy enough, it's simple to change the consistency, relatively low risk for allergies, and seems easy to digest... but new sources say there's a better way to go.

I'm now reading about how an infant's digestive system is not suited for grains yet. Not for a while. They say fattier foods like egg yolk, coconut oil, butter and animal livers are perfect first foods.

As I'm still in the beginning of my research I don't want to claim to know much at all about this. So, what's your opinion?
