I don't condemn Stella Creasy or any other working mother, needs must, my own mother returned to work when we were junior school age and I can remember us being latch key kids, not sure that would be legal now, but no after school clubs then. However, survive we did!
I would however reiterate what I stated up thread, the offices where I worked would never have countenanced babies and children being brought into work on a regular basis, why would they? It is a place of business after all and there are colleagues to take into consideration. From recollections, if children appeared in the office on the odd occasion, they tended very much to be children of the bosses rather than the rest of the staff, not usually babies, children and then only in exceptional or unforeseen circumstances.
I don't make any judgement about women who have children and return to work, equally I say the same about those who are stay at home mothers. I made a conscious decision to have children in my early thirties I'd been at work since late teens, I wanted to stay at home with them in their early years. I don't agree that children slot into your lives, I rather think it's the other way round, my days revolved around them and their needs, having boys it soon dawned on me from early years that spending as much time on outdoor pursuits when the weather allowed it was beneficial for them. How that would have slotted into a working day, even if in between times they sat quietly in the office drawing and colouring, someone tell me? Little boys are a revelation they spend much of their time fighting imaginary forces and spontaneously combusting, very, very, loudly! Not conducive to an atmosphere where one is having to spend time on the phone to clients I might suggest. Of course they could be quiet at times reading and colouring and often did us proud when we took them out to say Pizza Express with a word of warning "behave or we won't come again" but that was occasional, expecting pre school children to spend long periods of time on a daily basis pursuing cerebral activities in a quiet corner to fit in with my working life, even if I could have brought them along with me, and that only happened rarely when I returned to work for my husband and they were early school age. Prior to that I would suggest, some children need to expend energy, spending an entire day/s in an office, if childcare isn't available, would not be conducive to the child's wants and needs and the rigmarole of feeding, changing and settling a young baby took ages from what I remember, to free up that window of getting anything done before the whole process had to be repeated and with an older sibling's demands as well, impossible!
