How should the baby’s tongue be positioned for an optimal latch?

For an optimal latch during breastfeeding, the baby’s tongue should be positioned forward and down. This positioning allows the tongue to effectively cup around the breast, helping to create a seal and facilitate the transfer of milk from the breast to the baby’s mouth. When the tongue is forward and down, it can not only support the areola but also assist in the rhythmic motion needed to extract milk effectively.

Additionally, the forward position of the tongue enhances the baby's ability to suck properly, supporting both the baby's feeding efficiency and the mother's comfort during breastfeeding. An optimal latch contributes to better breastfeeding outcomes, as it can reduce the risk of nipple soreness for the mother and improve the baby's ability to get sufficient milk.

The other positions mentioned would not support effective breastfeeding mechanics, which is why they are not appropriate for an optimal latch.
