You could take it as an insult, but God does not credit us with being rocket scientists when it comes to taking care of the next generation. Instead he pre-programs caregiving behavior on the part of mothers AND he pre-programs babies to elicit caregiving from their mothers. An obvious example is how a nursing mother's breasts gush milk in response to hungry-baby sounds. Just in case she can't figure it out from the way her baby is frantically mouthing anything that gets near...her breasts start to tingle and next thing she knows, the front of her shirt is milky. It is not the most subtle of hints. But considering how tiny and vulnerable babies are, it's a hint to heed. This milk-ejection reflex subsides after the first few months of nursing. By that time a nursing mother and her baby have sync'ed up well and the mother knows her baby's subtlest signs of need for nursing.
But it doesn't stop there.
