"Do you think they can leave one baby to cry because its keyworker is changing another of her charges nappies?" - well prsumably SAHM with twins, triplets, three under three (like my sister had) manage 24/7, why shouldn't a nursery carer manage it for more limited hours and with colleagues for support.
Please don't use the "attachment" issues argument - its facile in this situation. My son spent the first year of his life in an institution with rotating carers who did 24 hours on, three days off and usually 2 carers to about 12 children ie he was "raised" by about 8 differnt carers who then changed every six months as he moved into older rooms. I know about attachment issues and have had to deal with them myself in real life. I have never met a child in the UK who spent even 10 hrs a day at a nursery who appeared to have any attachment issues at all, the only children I've met in the UK with attachment issues were as a result of extremely neglectful parenting.
The ridiculous trotting out of "attachment" when nursery care is mentioned to try and prove that nursery care is the spawn of the devil.
Well despite care significantly worse care for the first year than the home/nursery combo talked about here, my 4 year old son is now a happy settled well attached and pleasant child, because actually his care was kind and relatively stable and he was well treated. Decent nursery provision being derided as bad for a child is so laughable - when did we become so precious about wht constituted decent child care?
My friends are a combination of SAHM, WOHM using nursery provision and a childminder, part-time workers and one who works from home (or shirk from home as she likes to call it). You couldn't pick out the well balanced, well attached child of the SAHM from a line out of all the others. Because they aren't significantly different.
