Shulchan Aruch (YD 124:1) states:
A Nochri child who does not mention idolatry or Meshamshim, if he touched wine he forbids only drinking it, but not benefit from it.
(See this related question.)
Would this prohibuition be only in the case of a gentile child who is an idolator or also in the case of a non-idolatrous one — i.e. would the wine be permitted to drink if a non-idolatrous gentile child touched it?
