He was breast fed, and only rarely used a bottle... and when we did we used high temperature water only sterilization, never soap.
The reason he was crying is most likely that he was a big baby, and wasn't getting enough milk initially.
Not your son specifically, it's just a crying trigger overall, along with the other classics like gas.
> only sterilization, never soap.
Sterilization is a bit oversold. It's the most useful the first time you use a bottle, after that it has diminishing returns.
In general, parents are oversold pretty much everything.
> wasn't getting enough milk initially.
It's common in the beginning. "Mother's milk tea" is great to increase milk supply, but I can see it's not an issue now.
Enjoy the baby, they grow fast.
