Help with newborn!

Jessica
My daughter is a little over a month now and lately during the day she just wants me to hold her. Even when she falls asleep in my arms and I lay her down in her swing rocker or bed she wakes up crying and crying. 
I pick her up and she will fall sleep again so forth and so forth.  Can anyone help with suggestions. I have a 2 year old son so I can't always just be holding her.
