If you are this upset about it, why change? Also, if you are this upset, how do you think your dd feels? As a long time daycare provider, I know the importance of continuity for a child in daycare. She has been there half her life, so switching will be a very big deal for her, and she is obviously already concerned about it. Is wanting more of a preschool program really that important? Since she has an August bday, it will be another 2-3 yrs until she starts kindergarten. She has a long time to do more preschool activities before starting kindergarten. Kids are only young once and so many parents push school on them at a time when play should be more important than worksheets. Even if your current provider does not run her home daycare like a preschool, she is running it like a home, which probably is one of the reasons you chose her daycare. Children can learn the exact same material at home - or in a home daycare - as they can in a preschool classroom setting. As a daycare provider, it bothers me that you haven't talked to your current provider about this. Shouldn't you at least talk to her about your want for more preschool activities and give her the chance to offer that before finding new daycare and just giving your provider 2 weeks notice? You say there is nothing wrong with your dd's current care and she has been there a year and a half, is it really a necessity to move her? And is it more for her or for you to have her somewhere more preschool focused? I hope I don't sound mean, I just have had the same thing happen in my daycare, parents pull their child out for something more structured, but they have also come back, saying their child wasn't happy elsewhere, they weren't happy, and they wish they would have never moved their child and had their child go through all that stress and trauma. I stress talking to your current provider, letting her know what you want and at least giving her the chance to offer more. If the provider chooses not to offer more, and you still feel the need for more, at least you have given her a chance and she knows how you feel.
If you do still move her, IMO, I would have her visit a few times, with you, and show her how fun it is there, and how comfortable you are with her being there. When you start her, I would have her start full time, full days, if that is what is going to be normal. It is typically easier on a child to start with a normal daily routine, rather than doing a few hours or a half day - that ends up confusing the child about when mom/dad are coming to pick up.
Whatever you decide, best of luck to you and your dd.
