This study focuses on the influence of infant chronic idiopathic colitis (CIC) on maternal care in rhesus macaques. Subjects included 146 mothers-infant pairs observed as neonates, at 3 months, and 6 months of age. Focal observations were collected at month 0 (neonates), month 3 (young infants), and month 6 (older infants) (81observation hours). Subjects included ‘chronic’ diarrhea infants who were treated three or more times in a calendar year (2009-2010) and healthy counterparts. Analysis of Variance (ANOVA) was used to consider the effect of age and diarrhea episodes on maternal behavior. Infants approached and made contact with their mothers more often with increased age (from 0 to 3 to 6 months) and began to move away from their mothers and develop infant independence [Infant Approach: ANOVA F(2,137)=9.52; P<0.001; Infant Make Contact: ANOVA F(2,137)=9.26; P<0.01]. Mother’s supported infants in a ventral clinging position at 0 months but at 3 and 6 months this significantly decreased [ANOVA F(2,137)=6.54; P=0.002]. However, mothers supported ‘chronic’ infants in a clinging position more frequently at relatively older ages (3 and 6 months) [ANOVA F(2,137)=4.55; P=0.012]. There was also a trend for mothers to solicit ‘chronic’ infants to climb onto their mothers more often compared to other infants [F=(2,137)=2.80; P=0.06]. Results suggest mothers may be more protective of ‘chronic’ infants and this may influence the development of maternal independence.
