Okay, I can only say what worked for us when my DD was little.

We made sure to have a one on one time first thing in the morning after breakfast. This is where I would forget everything else that needed to be done and sit down for about 20 minutes up to an hour just playing with my DD. I found that if I gave her this time, she was happier to do things on her own more throughout the day. It was a good opportunity for skill building as well.

My lifeline however, was "room time" in our routine. I bought a special countdown clock called a time timer off ebay. It's mainly used for autistic/ADHD kids but really good for littlies too as it is really visual and has a red disk that shows a count down that then alarms once it reaches 0. Everyday DD would be given special room toys to play with and was expected to play with them in her room for a set amount of time. At first we had to put her in a play pen, then when she was older and more mobile I would put a barricade in her door, then we eventually were able to remove that and she would just stay in her room until the timer went off. I started with a ten minute countdown and at first she cried and carried, but I didn't give in because it becomes what I call a cheap peace, in that trying to stop the crying here would lead to issues elsewhere, at a later stage at much greater ferocity. After three days of this being in her routine gave up and just played. In the end I was able to slowly increase the time to an hour - it was awesome! At five she can now quietly play in her room with her toys for hours on end (her choice).

Another thing I found great was putting her in her high chair and moving that into the kitchen while I cleaned up, cooked etc. She would be given 2-3 toys or books to play with on her tray while I worked. I also narrated what I was doing. This way should could be with me and involved but not in my way.

That's all I can think of at the moment, HTH.
