1156 Am I getting pulled into the turnings of Frege’s triangle?
Here is a picture of Frege’s corner 2a for this application.

1157 This corner pertains to all the agents in the family and, in an odd sort of way, the family itself as a cultural agent. The family (as a cultural agent) exploits the potential of triadic relations, in a way that differs from each person of the family. How so? To me, it seems roles (such as mother, father and siblings, as well as aunt and uncle) adapt to the family and the conditions at hand, while each person adapts to a role and the conditions at hand.
The contiguity of [symbola] designates one crucial role among a system of differences. There are various roles in family. Only one brings the matter of family belonging (SOi) into the form of where mother is (SVs).
1158 This is precisely what Comments on Michael Tomasello’s Arc of Inquiry (1999-2019) (by Razie Mah, available at smashwords and other e-book venues) elaborates, but not in regards to the social circle of family and friends. Tomasello discusses the social circle of the team.
The family works as an agent (composed of agents). So does the team.
1159 The next side of Frege’s triangle for a newborn looks like this.

1160 The location of mother2a (SVs) stands for where the infant attains food and safety2b (SOs) in regards to the self-governance of the family2b operating on potential courses of action1b (SIs).
1161 Mom, the person2a (SVs), is specified through the role of the one where the infant attains food and safety2b(SOs). The materiality of mom and infant are entangled in an immaterial specificative sign. And, this turns out to be exemplar.
1162 Next, the inquirer passes Frege’s corner 2b. For semiotic agency, this location is information2b.
Here is a picture.

1163 What information2b is the family gathering?
The innate expectations of the infant are satisfied with mom, in a most mammalian sense, (SOs) [referentb] what the person of mom is doing (SVe). She is doing far more than providing milk and comfort. She is participating in the construction of a “cognitive niche”. Here, “niche” is the potential of ‘something independent of the adapting hominins’. That ‘something’ is triadic relations.
The person of mother2b is like matter. What mother does is like form2b. The substance of information2b is Frege’s [referentb]. Matter [referentb] form. Mom [isb] what mother does.
1164 Indeed, the family as both social circle and agent corresponds to what scientists label, “niche construction”. In the Lebenswelt that we evolved in, the agent of family culturally endorses motherly behavior that signifies what mother is supposed to be.
