Is my niche too narrow?

I coach moms to yell less and play more. So I geared my copy on my site to yelling at your kids and how that affects everyone. I want to coach moms to take care of themselves first, have more self-love and how that will have ripple effect. All of your relationships improve. Especially the ones you have with your kids. We have a few clients but are trying to really target a bit tighter to hit a pain point. We felt like we weren’t gaining new clients because everyone knows raising kids is hard but not necessarily a sense of urgency. Just trying to get clear on getting more focused.
