It's not for me to judge other peoples choices, but 9 months?
A view from the otherside of the fence for you...
Our little one is 8 months - and has just had her first 2 days at Nursery.
Now she is crawling around and investigating everything, the childcare centre is set up much better for that than our home.
I am only too aware of the importance of teaching her that she can't go touching the oven or the bin or pull the books out of the shelf etc as these are not good things for her and therefore we have to set boundaries; however, I also don't want her to be so restrained that she isn't "interested" in anything. Childcare allows for a greater balance of these things than we alone can provide her in the confines of our home.
At the nursery, she can explore, with less concern on our part as to what she will get into - no kitchen or bathrooms etc. She can learn to share and interact (as she has no brothers or sisters... yet?) with others, not just immediate family and close friends (who in general are more lenient in some ways, through familiarity). She is also learning that although Dad and Mum are always there for her, we don't need to always be there, physically. For us, doing that at school is a big change rather than the more gentle, incremental one child care offers. School will still be a big change - "why make it harder?", if you will.
As the primary carer/stay at home Dad, I can work a few hours a week now, which means a bit more money to do more things with her; we can afford swimming every week, not every fortnight. I can afford a few different toys and books for her to keep her interest etc as she grows out of her current ones. My wife and I can do things we want to do for ourselves more readily, which means we are happier, healthier and more relaxed, resulting in a more positive homelife overall for her to be raised in, in our case.
She is still the main focus for both of us; I have told my employer so, so they are well aware that I may well have to drop everything at times to go get her - the same applies for my wife.
Just some thoughts for you...
@Hora - I have to say, I agree with those that also find it funny you can rant on here, but not spare the time to go check on the little one...
But I also think that if you aren't that happy with the nursery, change it. If we get crap service at an LBS we go elsewhere and that is only for a bike - for our kids we should be ever more ready to make any changes we see as necessary.
