Narrowing my niche but I am a seamstress

I need help on narrowing my niche- I kinda just have been sewing whatever I feel like it in no specific kind of fabrics for the past 5 yrs and I’m finally feeling like I should specialize in ‘something’. I am a stay at home mom that sews and sells my clothing/baby blankets/headbands on Etsy and in small boutiques. I don’t really have a niche – I sew sizes preemie-12 yrs. for both boys and girls, some organic, some not, in all deigns of knit fabrics. I offer custom orders, and love doing custom orders so people can get their outfits made exactly like they were looking for. How do I narrow something like this down? If it’s not health, wealth or relationships? Thanks for your thoughts!
