We have double pane windows in our almost 4 year old house. The inside
of the window has lot of condensation and water drops forming and
collecting on the window sill. Is this normal?

Depending on the temperature outside, yes.
If you go much below zero Fahr. triple glazing
is your only escape. (You would not like indoors
a humidity low enough to prevent condensation.)
