Anna I'm sorry you don't have a nursery local to you that are like the nurseries I have local to me.
It's great you can offer your DD the life she has and that you are happy with that before she starts school.
However not all children are shut up all day in horrid little rooms!
My DD's nursery was down a country lane and we drove past pigs and sheep every morning. They went out every day, weather permitting. They walked toparks, the farm in teh opposite fields, went on trips. They did PE with acompany employued to come in and teach them things especially, they learnt French again with a teacher bought in especially, had music lessons with a trained music teacher. My DD who has SN's came out fit, happy and healthy, could count to 20, know all her days of the week and month, knew loads of French words and everyone saw a huge improvment in her in some many ways. She has mnade firm friends with a few of the other children there.
She also knows her local town and we also take her to museums (a lot), go to restaurants with her, take her swimming, to little theatre shows locally, take her on the tube, to parks and 2 lovely local farms as well as the odd safari park or theme park now and then.
She has a full and varied life and that included her nursery.
So I'm sorry your local nurseries made you feel like crying, They are really not all like that. Mine made me cry but with happiness and when she had to leave!
