I just put all mine to the breast asap after the birth and then continued to breastfeed while in hospital and for a few days after coming home. That way they got the colostrum in the most efficient way. I did have discomfort after stopping the breastfeeds, but I think that if you are wanting to make sure your bub gets colostrum, then the best way is to just put him or her to the breast - unless you are going to be separated from the baby. After all, the only way to get the colostrum out is to stimulate the breasts, whether by the baby sucking or by expressing. So there is no way of getting around it really. It just depends on whether you want to physically breastfeed, or would prefer to feed bub the colostrum in another way.
