I reccommend Mother Goose Time because it has lots of great ideas and is very professional looking. Most of the projects are cute and easy to implement. I do have a few caveats...
1) I do tweak it (including the art projects) to make it more developmentally appropriate.
2) I use this because I need a parent pleasing curriculum, and I do not have the time to prepare it myself. I do not have the time to print stuff off, look on pinterest, and put together a wonderful curriculum. I have done this in the past and will go back to it just as soon as I have some more time to devote to it.
3) It is a bit expensive and at the end of the month I see how much was wasted because I truly do not have the time to do it all. They provide a lot of stuff.
If you want to see some of the projects we do with the curriculum you can check out my facebook page.
