We haven't had sex for 6 months now and our sexual activity has reduced, especially after the baby was born. Is it okay?

I think there is no right or wrong answer. It is good to maintain regular sexual activity for married couple as not only does sex helps to improve a couple relationship, it also a good exercise to relieve stress. However, a couple should not be too stressed about not having sex after 6 months as it is normal that sex activity reduces after child birth. Often married couple get too caught up with taking care of baby and daily commitment and may neglect their sex life. It is recommended that couple let someone else handle the baby once in awhile to enjoy couple time such as late night dating to create the mood for sex.
