PLEASE! Stop thinking that holding your baby all the time will cause him or her to be clingy! That's just not true!
Some tribal mothers always hold their babies until they can crawl (called the in-arms phase), their children are so independent! The Continuum Concept is an excellent book all about this.
Toria, what you're doing is called Attachment Parenting. Here's a bit of information from https://parenting.ivillage.com/baby/bparentstyle/0,,489j,00.html
The term, "attachment parenting", was conceived by pediatrician William Sears and his wife Martha, to describe a highly responsive, attentive style of caring for a child. Attachment parenting promotes physical and emotional closeness between parent and child through what the Sears refer to as the "Baby Bs." The Baby Bs are bonding, breastfeeding, babywearing, bedsharing and boundary building.
Attachment parenting advocates encourage parents to hold their baby often in the early sensitive weeks of life to foster bonding. Breastfeeding is promoted because it enhances the mother's natural instincts to respond to her baby through physical closeness, hormonal influences and promotion of attentiveness. Both babywearing, the practice of carrying the baby on the parents' body with an infant carrier or sling, and bedsharing, parents and babies sleeping in the same bed, provide additional opportunities for closeness. Boundary building is a discipline philosophy that entails responding to the genuine, age appropriate needs of the child and using gentle guidance. All of the Baby Bs are aimed at promoting a trusting, intuitive relationship between parents and baby through the physical and emotional closeness that makes it easier to know and appropriately respond to the baby's needs. While some people might see the Baby B's as a set of rules they must follow, they are just recommended tools that can and should be individualized for each family and parenting situation.
CIO is a cruel practise that makes your baby mis-trust you. "William doesn't cry anymore; he knows no-one will come"... remember that NSPCC advert?
