Final answer:
To calm a 2-month-old baby, carrying them in a sling and using a rattle can be effective, but wrapping them in a blanket is not recommended due to SIDS guidelines which advise against loose bedding.
Step-by-step explanation:
To soothe a 2-month-old baby, there are various strategies that one may employ, taking advantage of the infant's well-developed sense of touch. Carrying the baby close in a sling or distracting them with a rattle are both effective methods, as they can provide comfort and engagement. On the other hand, offering a pacifier or the breast 'whenever they want' may not be advisable as it could lead to problematic feeding patterns or dependency issues. Importantly, wrapping the baby tightly in a blanket is not recommended due to the risk of Sudden Infant Death Syndrome (SIDS), where it is important to avoid the use of loose blankets in the crib to prevent suffocation risks. Instead, parents are advised to ensure a safe sleeping environment by placing babies on their backs to sleep, in cribs free of loose bedding and other items that could be hazardous.
