I'll pick another point....breastfeeding is actually a rather beautiful solution to the winter lack of food intake. During the year, Mrs Grok eats enough to build some fat stores (aided by pregnancy hormones that make it a particularly efficient process, as Mrs Korg bemoans regularly!) Breastfeeding taps those fat stores. It's like a reservoir during the rainy season supplying water during the drought.
One question: where does the information come from that the Groks spent their winters babymaking?
