How long does the extreme clingy stage last?

Ashley

I heard about this stage...but now I'm living it. My daughter is almost 11 months old and will literally scream and cry if I am not holding her. Being right next to me isn't even enough. I'm getting wore out... It's like the newborn stage all over again where I can't get anything done. I love the cuddles but the extreme crying and screaming if I'm not holding her is making me crazy.
