OP If you're in the NW you can begin to build on your daughter's innate brilliance with very little expense (ok some expense...) Right from now.
Have you looked on the Bridgewater Hall's website? Book tickets for the Family Christmas Carols. Lovely for a one year old.
The John Rylands Library usually has something similar - may be free.
Manchester Art Gallery has an interactive kids' area. Take her next year - and keep taking her to see more and more.
Manchester Museum ditto.
The Whitworth Gallery + lovely outdoor space and cafe.
Next year take her to Manchester Museum of Science and Industry.
Sign up to the Royal Northern College of Music mailing list. Get into the habit of going as often as you can.
Leeds Art Gallery?
Tropical World - Leeds?
The Grand Theatre?
West Yorkshire Playhouse?
I could go on... Honestly OP - You can get endless advice here on schools - I second most of what's already been posted. But wherever you send her to school, it's the sort of things listed above that will make the crucial difference in the early, early, early years. Don't wait. Don't think "she's too young for that" or "she won't sit still, " or whatever. You're really lucky to live where you do - expose her to all the good stuff and you can be far more confident in your school choice later on. And she will get far more out of her formal education because of what you have done and continue to do.
