We only recommend that you start munching on our bars once baby has been delivered. Naturally it may take a few days for your milk to actually come in (could be up to 5 days).If it is baby number 1 and you are not sure, why not have some in your hospital bag as a delicious snack if you need them.If it is baby number 2 and you had issues first time around, start enjoying as soon as baby has been delivered. We also have a blog for you to read on how to prepare for breastfeeding while pregnant, you can read it here
