HI! I have an 18 month old. There are times when she needs me close and I need to get things done... just like you. I found a baby backpack at a yard sale and this has been fantastic. I pop her on my back and ask her to help mama wash dishes or cook. I give her a cup, a spoon, something. Then I can tickle her with my hair and keep working or tickle her foot or play boo now and again. I also happen to be pregnant and I now am not able to put her on my back so I have found that sitting with her for an intense, focused, fun 5 minutes reading a book, tickling, talking, etc. followed by a way for her to "help Mama" satisfies her. If I am cooking, I give her a bowl and a spoon near me on the floor and she stirs, or I put an apron on her and she marches around me, or if I am cleaning I give her a rag and she "scrubs" the wall near me. I talk to her all the while. Another thing that goes far more and more is taking her for a few minutes of fresh air to visit the dog next door, throw the ball, see the airplane in the sky. Again another fun 5-10 mintues followed by something to do with Mama while she is working.
Good luck, J.
