I've only skimmed the article...but I think he's got a point. I think (know) it would have been detrimental for DS1 to have attended a nursery. (He did go part time fro 2.5) Although that was purely my choice, and I may have been (with hindsight) selfish.
DD attended nursery from the age of 2....I now really regret that she went so young, but I was doing the "I need to work" thing at the time, as was DH.
I think it's a good thing that articles like this are published. Yes it makes uncomfortable reading...yes working mothers who need to use nurserys, how ever excellent, will shout bollox, but I think we need to be really, really honest, and make sure our grandchildren, if not our children have the very best care possible.
I'm pretty sure it's healthier for children to be looked after by childminders and even grandparents (depending on the grandparent of course) than for them to attend a nursery. But for some reason I still chose a nursery for DD. At the time it was a very small nursery, with maybe only 12 children at a time. It was lovely. Then it decided to expand...move to larger premises and take on more children, and I could see that it really wasn't ideal for children to be in such a large setting. I can't remember how many children no, but between 20 and 30.
So yes, we will need child care in the future, but we need to make sure it's as child friendly as it possibly can be. And if we listen to articles like this, it means perfect child care won't be cheap.
