Frozen colostrum

I have some frozen colostrum saved and I’m not really sure what to do with it. Save it for a rainy day? Go ahead and give it to her? I’ve been told a lot of benefits to having some saved colostrum but not really sure what to actually use it for. My little one is 9 weeks old now and is mostly breastfed except the occasional bottle when I have to go out. I have plenty of regular milk frozen for her just wanted to know what others have done with their saved colostrum.
