Try different physical positions. If you're cradling her in your arms, try putting her up on your shoulder. Or vice versa.
Other things to try are: football hold -- her chest on your base of your palm and side of head on your fingers; football hold on back; lay her on her back on something firm/hard like dining room table or desk (be sure to turn her head) or on something super soft like a quarter folded comforter (do not lay face-down on super-soft as it's thought to be a cause of SIDS).
Obviously, steady her as needed. football on back pretty much requires a 2nd hand to steady. The head usually sets well between index and middle finger, with thumb and other 2 fingers around the shoulders... man I forgot how tiny 1mo old kiddos can be. Thanks (=
Try also giving her to dad to lay face down on his chest on the couch. Sometimes the mommy-boobies can be too squishy. My kids never liked it. I think it's all about the heartbeat.
If you think it's a hunger cue, put the tip of your li'l pinkie finger in her mouth (nail up). If she starts sucking hard, then it's time for chow. Personally, I never had the kicking with hunger, it was always kissy-mouth smacking with head turned to the side.
Let us know what happens.
edit: oh... uh... welcome!
