When will it get better?

Jamie
I am a first time SAHM of a beautiful 2 and a half month old. Her sleeping is getting better at night but 90% of the time she is awake I feel like all she does is cry. She 5 weeks early and in the NICU for 8 days. She has doubled her birth weight and as grown 4 inches. I feel like I am not doing something right with the amount she is crying. I do my best to entertain her and make sure she gets what she wants but I am having a hard time telling when she is hungry with the amout she is crying. Today has been a bit better, although we didn't go anywhere yet today. I am about at the edge when it comes to the crying. Anyone else have these issues? I keep thinking it will get better when she can entertain herself a bit and hold on to things.
