My 8 months old girl is driving me crazy. I can't put her down for a sec. She will scream and cry hysterically whenever I put her down. She wants to be carried all the time! What's wrong with her? How do I get her to stop this?

Sounds like my son! He's at the stage where he has to always be carried or never left alone even for 1 second and this can get really tiring and frustrating. You can consider babywear your daughter while you do your housework. Or, you can start small.. leave your daughter in the room and keep talking even until you leave the room so that she knows you are still around. Keep doing this and it will slowly get better.
