Like Roopashree said sometimes after the birth of a child,  you lose your sex drive,  it is very normal.  have a heart to heart conversation with your hubby.  Baby steps, it is like the first time all over again.  slowly,  you'll get your drive back. 

alright tysm

It takes little time to settle with harmonal changes and body urges. Now you are in " Motherhood" mood. Don't worry. Try to relax..ease the tension inside you. Slowly you will be fine. Talk to your husband regarding your mental state gently. Hope he will understand.
