Nothing in a child's brain tells her to whom she should attach. Nature's assumption, if we can put it that way, is that the parents will be consistently present. Children are born with this expectation coded into their bodies and nervous systems. The immature brain cannot abide what Gordon Neufeld calls an "attachment void -a situation in which no attachment figure is there to connect with. Inevitably, just as a newborn duckling, in the absence of its mother, will trustingly follow the first creature it sees -the nearest goose, squirrel, park ranger, or even a robotic toy car -the vacuum must and will be filled by whoever is around.
