Carrying her everywhere you go is unnecessary and sends her the wrong message. Responding to her every cry by picking her up and soothing her gives her the wrong kind of "power". It's not a good lesson to teach. Why don't you break this pattern over time? When she cries, pick her up for just a few minutes, cuddle and soothe her, and then put her in a playpen, perhaps with a musical mobile. You could also place her in a safe infant seat so she can watch you while you do things. You can engage her by talking to her, singing to her, making noises, etc. Your baby should not remain in a playpen or infant seat for long periods of time and you should not be a slave to her every cry.
Your baby may want you to hold her all the time but she doesn't need it. I know you can feel great guilt by not picking her up when she cries, especially when your holding her can immediately stop her crying. Trust me, she will learn to cope with the different ways that you attend to her.
On a parting note, when you do bring her to see your family, let them know how you are handling her cries and ask them for their cooperation.
