K.,
first this is NORMAL-age appropiate behavior..not a product of any parenting style:) Sometimes, singing or talking when you are leaving the room helps them learn that you are not "gone" Also, exposing her to other people when you are not leaving is good. Support group is a perfect example..put her down let her play and you are still there. Some moms when their babies get so clingy feel like they have to get out..but babies sense that and cling more! I certainly think she is also picking up a bit on the change in the household, she just can't say it. Lastly, it WILL pass..all too soon:) Just keep working with her, 5 minutes turns into 10 then 30 etc and next thing you know she's playing fine before she realizes you are gone. Also, let her have short play dates with someone she really knows...like your sis. Go somewhere for an hour and she gets used to you being gone. Hang in there girl!
