Order the logic of weaning conflict, from the parent's care to the observable clash.

1. The parent begins providing care to its current offspring.
2. Continued investment increasingly costs the parent's future offspring.
3. The offspring (r = 1.0 to itself, 0.5 to a future sibling) still gains from more care.
4. The offspring demands more than the parent is selected to give.
5. The disagreement shows up as weaning conflict and tantrums.

Care is given, its continuation costs future offspring, but the offspring still profits from more (valuing itself twice as much as a sibling), so it demands more than the parent will give - producing weaning conflict. The tantrum is the visible tip of a relatedness mismatch.
