I have been so busy and not around much this summer, but what a timely thread. DD1 has just started a half day Montessori program, and I am in grad school. She was previously at an all day daycare.
I need activities she can benefit from while I am on the computer in the afternoons. She loves TV, and I admit to having let her watch more than I usually would, though I limit her choices (she is enjoying Frannie's Feet and Pinkie Dinky Doo right now)...
I do have an iPad but haven't updated apps much since she was a 2 yr old, and many of those are pretty easy for her now. I will be looking for the apps DAD22 mentioned, and any others - please keep them coming. As well as any ideas for other activities. She is very into painting right now and we are going through paint like crazy. She asks to do it nearly every day, which we do. I also take her outside for a while, especially while it's still summery and nice. And I want to take her to a local museum/kids place/etc once a week or so.
Of course, in a few weeks time, when she has settled into the Montessori, maybe she'll be content pouring things. Who knows. But more ideas are great!
