Do people really think 2-3 hours of tv is so unreasonable the little boy would be better in a nursery 3 long (what 10 hours?) a day?
Well, research suggests no TV at all for under-twos (not that that is something I have managed to abide by myself and I am not some TV-is-the-devil type)
Regardless, I think what you are suggesting in that statement is that nursery is some sort of last resort and something negative.
In my experience it is not at all - in fact it is a positive.
I don't have to send DS to nursery. DH is at home and could look after him but we choose to send him for 2 full days a week. And have done since he was 5 months old.
To my mind, the benefits are enormous. DS loves it. There are so many different activities and experiences that with the best will in the world we simply could not recreate at home.
They do arts and crafts, baking, outdoor play, messy play, soft play, quiet play, reading, trips to the park, picnics, music time, dance time, have a rabbit, have animals brought in from local farms (piglets last week), etc, etc etc.
We do do these things at home, but can't sustain it for 8 hours solid due to having dull life stuff to attend to (house work, cooking, shopping, home admin etc). Much like the OP we do our best when he is at home and try to do as many activities as possible, but there are always going to be times when something needs doing and the focus cannot be on him. Which is generally when the TV comes in. Nursery doesn't have those distractions (and certainly doesn't have a TV) so DS gets a full day dedicated to him.
Not only that, DS in an only child and likely to remain one, so nursery gives him a great opportunity to socialise and play with other children.
At 18 months he is speaking in full sentences and is confident, independent and gregarious. A lot of which I put down to nursery. He cheers when we get there and absolutely thrives on it.
Of course, much depends on the quality of the nursery and the personality of the child but this "home is always better" stance really puzzles me. It isn't. There are some god awful homes out there and some excellent ones. There are some god awful nuserys and some excellent ones. It isn't a definitive that one is better than the other.
For me however, an excellent nursery has real benefits for a child. And that is why I choose to send my DS even though I don't need to.
I think from the sounds of it the OPs child would get more benefit from nursery 3 days a week and home 4 days a week than just from home 7 days a week, but it does of course depend on the quality of the nursery, the child and how the OP feels.
