She is utterly dependent on you to meet all her needs, both physical and emotional (security) for many months yet. You cannot possibly ruin an infant by giving her too much love and attention. That's something you might look at again when she's a year or so, but not now. Babies do not develop bad habits. It's much too early.
Give her the connection and comfort she needs now, and you will eventually have a more secure and less needy baby than if you underindulge her in her earliest months. She is asking only to have her needs met, and fussing, writhing, and crying are the only means she has to make her needs known.
I hope you'll look into the methods used by Dr. Harvey Karp, author of The Happiest Baby on the Block, who explains why he calls the first 3 months the Fourth Trimester, and explains why babies run pretty much according to their own needs for the first 3-4 months. Here are some useful short videos:
