VBA Auto Sort The Column

I have the below small code which auto sorts information in column A & B but I am having trouble trying to get it to sort from row 3 and not sort the first 2 rows. The first row is the column header the second row I want left blank and then sort after that.

Plus at the moment after I enter something into column A it auto sorts itself but what I would really like to do is have it commence the auto sort after I have entered information in column B and pressed "enter". Because at the moment I enter info in column A then it auto sorts itself then I must then find it and then enter the info into column B.


Private Sub Worksheet_Change(ByVal Target As Range)
Dim rg As Range
Set rg = Columns("A") 'Column containing names to sort
If Intersect(Target, rg) Is Nothing Then Exit Sub
Range("A:B").Sort key1:=rg.Cells(1, 1), order1:=xlAscending, header:=xlGuess
End Sub
