1) Age < investment a lot while grandkids >
2) More dependent children = less care per grandchild
3) More grandchildren = less care per grandchild esp the younger grandkids under 2 years
Support is diluted, not absent - but heavily constrained by demographics

High fertility rates (TFR = 7.7) mean Agta grandmothers can have up to 30 grandkids, creating competition 👶
More grandchildren = less investment per child 📉
Our models showed that grandmothers with more young grandkids decreased investment by up to 34%

Given high mortality rates many grandmothers were dead (~45-55% kids had dead grandmothers) and after the age of 60 face poor health which limits investment ☠️
Grandmothers aged over 60 did basically no childcare!

We have moderate evidence that more foraging was associated with lower fertility (plot A) while increases in farming (plot B-D) strongly associated with increased fertility but as you can see the trends are not consistent in all populations
