Everyone's different

So after reading that a friend of mine did the ferbering method (the child screams then soothes themselves to sleep without the parents) after the child turned 10 months, I started to wonder, how does the rest of the world go about it?

Another friend spoke up and she said she had her daughter in routine after 3 months....

Another said when they were hungry, I feed them, when they were tired, they slept, we got into our own method...makes sense to me? 

I guess my issue is...all 3 moms stay/stayed at home and could experiment with their children and once the found a routine that works, they stuck with it. 

I know we are going to have to figure out our own system as well, but I would like to do it before I return to work...the one that makes the most sense to me is the one that says, they're tired they sleep, they're hungry they eat...but I'm not sure if that will guarantee a happy household. And I damn sure don't want to be that mom who stays up all night with baby to turn around and go to work all day with kids...even though were already stocking up on coffee just in case...

Priority 1- figure out a solution that guarantees a happy household, nobody needs to be exhausted worn out and agitated everyday

Priority 2- adjust baby to that schedule accordingly 

Happy baby, happy home. 

Peace and Love
