In the past, I have frozen colostrum antenatally because I had GD. It does freeze just like EBM - I think it defrosts quicker and that is the difference. Due to the high levels of fat in colostrum, it can defrost transporting it to hospital. Mine had to be packed in ice to get it to the hospital without it defrosting. You also don't have to get much at a time for it to be effective. I think they still prefer new mums to do as much feeding as possible and expressed colostrum is used as a top up otherwise they give formula.

I have expressed for two babies now and have never experienced contractions as a result of it but I think every woman is different. I expressed under advice from the lactation consultant from 36 weeks.

Good luck with the upcoming birth of your baby, Dansta. Looking forward to your birth announcement
