A baby is a bundle of joy but you and yoour husband have to rleate to each either as partners and parents in your new role.
I am not saying you have post natal depression but this organisation has information about coping with your new roles as parents.

It is only a few months and you both are tired and hopefully can learn to support each other.
Is there a time when baby is asleep when you can both sit and talk calmy .
Also do you have a local GP you could talk to.
