: Although weaning forms a crucial phase of an infant's life, there exists a data vacuum in the scientific literature regarding the awareness, perception, and onset of weaning among caregivers in the Kingdom of Bahrain. This study aimed to fill in these gaps and expand the information base of caregivers and clinicians by providing valuable insights on the Knowledge, attitude, potential factors, including sociodemographic aspects and the current trends/practices of weaning among caregivers in Bahrain. The cross-sectional study was carried out at fourteen randomly selected local Mother and Child Health Clinics (CHCs) in the Kingdom of Bahrain. A total of 253 caregivers capable of communicating in Arabic and English and with infants between 6-24 months were included. Detailed demographic data was collected, and all study subjects were instructed to fill the knowledge, attitude and practice assessment questionnaire. Responses were analyzed using software R v4.1.0 and Microsoft Excel. A Chi-square test was used to check the association of demographic variables with knowledge, attitude and practice. P-value ≤ 0.05 was considered statistically significant. Although a significant number of the subjects had an excellent positive attitude (67.59%), a high number of the subjects had inadequate knowledge (58.89%) and followed inappropriate practices (54.94%) concerning the introduction of supplementary food. The mother's education level and order of the child were significantly associated with knowledge, attitude, and practice. More prenatal and postnatal health promotion activities are required to shed light on the benefits of the timely and appropriate introduction of supplementary food..
