What is the difference between Vてはじめる and はじめてV meaning?


例えば：  
１．子供のとき、コーヒーをはじめて飲みました。  
２．子供のとき、コーヒーを飲んではじめました。  

I think both mean "When I was a child, I started/tried to drink coffee."

And how do I say "I drink coffee for the first time"?




[初]{はじ}めてする means _I do for the first time_. しはじめる means _I start to do_.

しはじめる implies that you are doing that now.

So, sentence 1 is "I drank coffee for the first time" and 2 is "I started to
drink coffee."

In addition, 飲んではじめました is unnatural. 飲みはじめました is natural.
