Is the emission of semen following arousal from a child sitting on one's lap considered an act of sodomy?

Sodomy is one of the most heinous and detestable abominations to Allah. What is mentioned in the question is not sodomy itself, but rather its مقدمات (preliminary acts). One must repent to Allah by ceasing the sin, regretting having committed it, and resolving never to return to it. To remain steadfast in repentance, one must avoid the causes of sin and sever the paths that lead to it. Regret and distress over the sin are among the greatest pillars of repentance, and they should serve as a motivation for steadfastness and diligent effort in righteous deeds. One must be wary of the whispers of Satan that invite despair, for repentance erases what came before it, and the one who repents from a sin is like one who has no sin.
