In English you need to take all the "h"s with a grain of salt. ;) (besides at the beginning of the word, because then will sound either very posh and french like or quite the other side of the spectrum more working class associated.) (I wanted to give examples, but you might read them in the wrong accent haha)
To complicate things further, in standard Dutch it is pronounced differently than how it is spoken in Belgium. the pronunciation of the g is one of the main differences between the languages.
