Shown separately, not part of the fit
Children who grow up in the same home are often surprisingly different, because the experiences that shape personality are mostly ones siblings do not share (Plomin and Daniels, 1987). Birth order, a favorite explanation, shows little or no effect on personality traits in large samples (Rohrer et al., 2015). Being different is normal for siblings; how you treat each other is the part you choose.
