When DD was born I had to express to establish supply as she was in NICU, some of this has been frozen since as I had oversupply. Sorting through today to get some defrosted for DH to give later. Earlier milk is a different colour as it was the initial milk. Is this ok to give now? It's within the 6 months date for frozen milk. It's more orange than my milk is now, more like colostrum colour.
