Snowflake child issue


I have looked pretty much everywhere for an explanation on how to create children, in my blocky I have a snowflake with physics enabled called snowflake yellow. The idea is that the snowflake hits the ground and then disappears while it’s children also do so in random sequence in multiple areas as a loop. So far nothing explains how to connect a Child index. So here’s my code if someone could help me that would be awesome.
