Alleged Effective Age for Using Cheese to Soothe Infant Crying
There are no research papers to assist in answering this question, as none of the provided studies mention the use of cheese to soothe infant crying. The studies focus on various other methods, such as:
- The five "S's" (swaddling, side/stomach position, sucking, swinging, and shushing sounds) 1
- Mechanical soothing using swaddling, sound, and movement 2
- Behavioral measures, manipulation techniques, and dietary treatments 3, 4
- Breastfeeding as a method of calming infants 5
These studies do not provide any information on the use of cheese as a soothing agent for infant crying, and therefore, it is not possible to determine an alleged effective age for its use.
