Cremation of my baby born at 16 weeks

Hi I ended up having to deliver my sweet baby boy friday morning 1/21 at 16 weeks. I already had a name picked out for him, zephyr. I was preparing my life for his arrival and unfortunately I had a lot of complications and had to deliver him early. I just want to give him a proper burial by cremation. My plan is to take him back to my reservation and have him next to my grandma at our family cemetery.
