Now that we have a baby, it seems it's the only thing my husband wants to talk to me about. We seem to have lost our previous spark. How do you reignite your previous relationship with a baby in the middle?

Give him some time to readjust. Having a baby is quite overwhelming and parents need time to adapt to this new life. Reassure him that their baby is going to be perfectly fine and he is doing a superb job. Once he gets comfortable with everything, you can slowly start discussing about other things with him. Take it slow.
