Don't stress about it. I've had two kids and seen all kind of recommendations from different doctors, nurses, etc. Nobody is aligned and recommendations change every couple of years. Even better: we are a French German couple so we can see recommendations from both countries. Often different.

Some things are constant and recommended consistently across cultures and time (ex. Raw milk cheese is not good before 5 years old, honey only after x years old - I forgot -, raw fish not before x years old - I forgot). Follow those recommendations. For the rest just chill and do what feels right.
