Is this weird or disrespectful?

I have one preschool son and a daughter who died at 22 weeks, I named her and we signed a certificate of life but not a legal one as she was under the viability age so classed as a late term miscarriage, however, I’m now pregnant with my third, and if it is a girl I plan to use my late daughters name as a respect to her and because the name holds so much love and value in my heart. However, when I mentioned it to my sister she told me it’s disgusting and disrespectful and just weird. I’m a single mother by choice (iui) and don’t know how to feel about it now
