What is the Lact-Aid Nursing Trainer System? Lact-Aid Nursing Trainer System is a tube feeding system created to aid breastfeeding by supplementing Baby at the breast. Basically, it consists of a container to hold supplemental liquid. A nursing tube reaches from the container to the nipple of the breast. Baby suckles the breast nipple and tube together. This accomplishes several tasks: It assures adequate nutrition & helps maintain or re-establish the special bond of breastfeeding! It helps Baby stimulate breasts more effectively...as milk increases, supplement decreases.
