Saw some pregnant mums sharing that their bodies have produced colostrum and they are using syringes to draw the milk out. Why does this happen? I thought breastmilk only comes after bb is delivered? Any method to get colostrum to come earlier? Worried about not having enough supply, or that milk comes late....... :(

I wouldn't intefere with the body's natural evolution. Colostrum is very high in carbohydrates, protein and antibodies and low in fat allowing it to be digested by newborns easily. It has everything a baby needs in the first few days so I wouldn't worry about milk not coming. After a few days, your transitional milk followed by mature milk will come naturally.
