sed – Replace only certain occurances

Problem:
I needed to change only certain occurances.

Solution:
Best explained with an example.

To change the first one.

$ echo "little kittens on a little boat" | sed 's/little/big/'
big kittens on a little boat

To change the second one only.

$ echo "little kittens on a little boat" | sed 's/little/big/2'
little kittens on a big boat

To change all the rest starting from the second one.

$ echo "little kittens on a little boat eating little fish" | sed 's/little/big/2g'
little kittens on a big boat eating big fish
