Question

Jimmys mom has many children. first is called april

Answer 1

1) In your first endeavor, you can find the solution as Jimmy as in the question, the name of Jimmy's, mother's child, i.e. Jimmy himself/herself is the kid. In any case, here too the question got its further logical inconsistencies, for example, If Jimmy is step-child of his mom and the question is reflecting about Jimmy's Step Mother's real child.

2) In our second probability we can expect that Jimmy's mom has named her kids on months name and as the arrangement proceeds After April, May come June and henceforth June is her next child, But the question signifies Jimmy's Mother and consequently, this again can't be your answer.

Henceforth you got a Paradox.

Be that as it may, with Simple approach Your answer will be Jimmy(it's given in the question)
