my DD has done this since she was about four months old until just recently. she still does it a little now, but is much more easily entertained by herself. she is 9 months old today.
honestly, during that time, nothing got done. the house was a wreck, i was a wreck... lol. i couldn't do anything until i had someone else there to keep the baby company. i couldn't wear her while doing house work because she didn't really like it (that was what most people told me to do on here). she used to be ok with her swing and watching some cartoons until i finished. all of a sudden, that wasn't good enough. she didn't want me out of her sight and wanted me NEAR her. i didn't necessarily have to be holding her, but i couldn't be more than three feet away from her at all times, literally. it's getting easier now, thank god. i have no advice for you, but i do feel for you because i am very familiar with that situation. lol.
