If your dd was an only child for 4 yrs. and is used to mommy playing with her, it may be hard at first to get her to do things by herself. I've seen many moms do this- lots of outings and activities when they have one child, then they have another and find out it is harder to keep up that kind of schedule. The best advice I can give you is to work on getting your dd started on activities. Interact with her, give suggestions ,ie, why don't you draw a picture of the pretty tree outside our window, see, the leaves are starting to change color, which color crayons match the color of the leaves, etc. When my dc were small, we rarely put the tv on but I was willing to read them storybooks anytime. That is something you can do while paying attention to baby. Homemade playdough is fun, as is painting. Just buy the basic colors- yellow, blue , red, maybe black and white to lighten/darken the colors. Get a paint palette so she can mix her own colors and paint. Some children do like workbooks and want to do the whole book all at once. If you do get a workbook , tear out a page at a time so she doesn't go through the book and pull out what she wants at one time. If she is used to you sitting by her side while she paints/ does playdough, slowly wean her off of that. Keep her at the kitchen table while you do other tasks in the kitchen. If you plan to send her to school, she won't be able to have the teacher's attention and approval all the time. Teach her to help you with your everday tasks. Not everything has to be play related, emphasize that you need her help and let her help as much as she can. In the long run
it is easier to integrate her into your daily life and tasks than for you to have your daily life child-centered and focused only on activities for the children.
