halacha - May one give a child a Meat meal on Erev Shabbos Chazon if they are always served on Erev Shabbos a meat meal?

Inspired by Tasting the meaty Shabbos food on erev Shabbos Chazon: can one swallow?

Per Mishna Berura 551:70 it is not permitted to feed children meat during the 9 days unless the child is weak. May one give a child a Meat meal on Erev Shabbos Chazon if they are always served on Erev Shabbos a meat meal? Perhaps this is considered their Shabbos meal where they may be allowed to eat meat?

Answer

Per Igrot Moshe OC IV 21:4 if that is the usual time they eat their Shabbat meal because they don't stay up late until after maariv, then they may consume meat as usual.
