    Stepchildren[edit]

    Does this property include stepchildren? Xaris333 (talk) 12:24, 25 July 2019 (UTC)[reply]

    Samo[edit]

    The second example, at the time of writing, says that the son of Samo had 22 children. I doubt that is what was intended. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 11:50, 29 June 2020 (UTC)[reply]

    Adopted children?[edit]

    Amy Coney Barrett (Q29863844) is a rather important item at the moment. She has five biological children and two adopted children. How should we represent this? {{u|Sdkb}} talk 06:15, 26 September 2020 (UTC)[reply]

    Oliver Wendell Holmes (Q360574) had no biological children and one child through adoption. I've tried using various qualifiers, but keep getting marked as constrain violations. What to do? Senator2029 16:54, 15 September 2021 (UTC)[reply]

    Time-dependent[edit]

    I propose that we can use this property with "time (P585 or P581/P582)" qualifiers indicating some history of the value (increasing all the time some baby is born). Infovarius (talk) 20:20, 7 August 2022 (UTC)[reply]

    Unit-dependent?![edit]

    It should not offer unit as additional option while filling in content for the property. 5.43.96.251 00:31, 30 December 2022 (UTC)[reply]
