I gave birth a year ago and my husband doesn’t want to have sex

Did he help with taking care of the baby. Maybe he is tired and no mood for that. We only had sex 2 yrs later and it was when we went holiday and jus the two of us because we want to have another child. At home, really no urge cause everyday take care of my child alr very tired.. Not sure about him but i guess no needs too cause he didnt say he want too.
