Collecting colostrum 38 weeks

i've been collecting colostrum for about 5 days now, i've been using sterile oral syringes to store them in the freezer but i've since run out...i read that colostrum can be in the fridge for 24 hours before freezing, just wondering if this is correct from mamas who have done this before?

this is my third baby, but my first time really focusing on breastfeeding, i feel more confident as a mom this time around so i really wanna give it a good go

can it be in the fridge for 24 hours before freezing? just wondering cause i wanna use my bags if i can, so can i collect over 24 hours and then freeze? (i know that i can't milk warm and cold milk/colostrum, id be combining them once they're both cooled in the fridge and then to the freezer)

TIA!🩷
