oldwomanwholivedinashoe, in my experience when my memory has failed me, and it has, something will happen that will make me think "did i lock the back door?" etc. So i would have thought if she thought about baby, that might have triggered "I don't remember dropping him off" and start a chain of events.
For this not to happen the woman must have been under a level of stress, whether from work, home, whatever that does not bare thinking about.
No-one should be left in a situation that stress levels get so out of hand. There are probalbly alot of people who feel some level of responsiblity over the babies death. All asking, could i have been nicer, helped more etc.
Loving your job is not the problem, its great you have one you do. For me leaving my children to go back to work was not an option i wanted to take up. Don't get me wrong i am not with them 24hrs a day, they both started nursery at about 18months as i know i was not enough interation for a child.
