Alternative in Python:

Code:
#!/usr/bin/python
data = open("file").readlines()
data.insert(1,'inserted line\n')
print ''.join(data)

Output:
Code:
first line
inserted line
second line
third line

Code:
sed "/first line/i\\
hi buddy\\
how r u ?\\
Gud morning" file

or if you want to add contents from a file use this

Code:
sed "/first line/r secondfile" file

Simply:
Code:
sed '2i Hello' file

This will return
Code:
first line
Hello
second line
third line
