Netanel was born in 1976 and is the oldest sibling. Shai was born in April 1978. Dorona's birth year isn't given, but she was old enough in 1980 to eat a Popsicle and refers to Shai as her little brother, meaning she was likely born around 1977. For their theory of their mother's affair to work, Yona would have had to have traveled to Paris twice and abandoned an infant to sneak off with Maurice within a few months of given birth. This seems improbable.
