As much as I’d like to just leave it at that, I’ll provide some information that may help bolster your confidence in dealing with those who might tell you otherwise. I’m pasting links below specifically from mainstream sources.
Notre Dame Research: ““Breast-feeding infants, responsiveness to crying, almost constant touch and having multiple adult caregivers are some of the nurturing ancestral parenting practices that are shown to positively impact the developing brain, which not only shapes personality, but also helps physical health and moral development,” says Narvaez.”
Babycenter: “Young babies are completely spoil-proof. Your baby needs all the care and attention you can give. Ignore the advice of well-meaning relatives who think babies need to learn independence. Instead, listen to your parental instinct — that inner voice that tells you to comfort your baby when he cries…If you give your baby prompt attention, he’ll feel more secure and less anxious, giving him the courage to explore the world on his own. And once he understands that you take his cries seriously, he’ll be less likely to cry for no reason. In the long run, responding quickly to your baby’s needs will make him less clingy and demanding, not more.”
Ask Dr Sears: (the whole article is really good) “In fact, both experience and research have shown the opposite. Attachment fosters eventual interdependence. A child whose needs are met predictably and dependably does not have to whine and cry and worry about getting his parents to do what he needs.”
LLL: “Mothers throughout history have always known, and research now shows, that babies are happiest, healthiest, and smartest, if they are kept in close contact with their mother or another family member most of the time. Asleep or awake, happy or sad, babies like to feel and smell your warm embrace. Research shows babies grow faster and learn about their world more readily when up on mother’s level. There’s more for the baby to see when he is with you while you go about your daily business than when lying flat in a crib or carriage. Babies cry much less and expend less energy that way. Many newborns sleep more deeply when held against your body. This type of approach is very respectful of your baby’s feelings, and is sometimes called ‘attachment parenting.'”
