You can really cover this information very quickly. It is mostly important to let parents know that others may expect the baby to sleep through the night very soon, but that is not typical and that feeding extra probably won’t help. Let them know how little babies can actually eat at one time. You can then ask them how they plan to get support for themselves when they get home. If they have developed a plan before the baby is born, remind them to use it. If they have not, connect them with someone who can help them think through their support system. You do not have to work that out with them in your short time with them. Suggesting a plan is just as important as giving the recommendations for safe sleep and breastfeeding, because without some help when they are sleep deprived, they may not follow through on implementing safe sleep and breastfeeding.
