Of course not! You absolutely cannot spoil a baby that age. The whole idea of an infant "manipulating" an adult is illogical - it will be years before they have the ability to comprehend that other people have feelings, an obvious prerequisite for "manipulative" behavior.
Her greatest need is your loving arms and your touch - not only for the sense of security and to promote a healthy attachment, but also because holding and touching your infant is the single most important thing you can do to enhance their physical and brain development. Specifically, at the lowest biological level, touching your infant stimlulates the growth of the brain's dendrites, which is vitally important that first year. Furthermore, research has proven that premature infants who receive more cuddling and massages thrive measurably better, and infants born with various medical problems had better clinical outcomes after receiveing massage therapy. Lise Eliot, a neuroscientist, has written a book called "What's Going on in There?: How the Brain and Mind develop in the First Five Years of Life" and she has dedicated an entire chapter on "the Importance of Touch." When I saw her at a lecture, she emphasized that the more you can hold your child, the better. She disdained the use of bucket car seats as a portable Laz-E-boy, (when the child isn't riding in a car, you don't need the carseat). The more you can hold them, the better for they will be pasychologically, emotionally, neurologically, and physically.
Add to the touch the warmth of mom's body, her smell, the sound of her voice and her heartbeat, and her milk - it should be obvious that there is not better place for a baby than in her mother's arms. I understand you may need to go the bathroom or take a shower or whatever. But realize when you put her down that it for *you* - don't do it for her sake. If it were possible to hold a baby constantly, it might make us insane, but the baby would surely thrive. Find a good sling! www.kanagrookorner.com
Our culture holds infants less than anywhere else in the world, (except perhaps Britian), and part of the reason is the misguided notion that it is good for the babies, builds independence, helps them learn to entertain themselves and similar hogwash.
Consider for a moment, that a baby born today in Bali will be held *constantly* by his mother or another family member for the first 4-6 months of his life, at which time he will have a "ground-touching ceremony", that is, when his feet touch the ground for the first time. Nice life!
