With a newborn baby in the house, especially if it is your first, there is so much to learn that you simply cannot replicate with classes, books and additional parenting aids. Every baby that is born will have its own unique traits, and although you can learn a lot from other parents, from books, from TV and a wealth of other sources, there is always the fact that what works with one baby may not necessarily work with another. However, this should not be viewed as an apocalyptic warning. As a parent, you will learn quickly how to deal with your baby, and they will form an attachment to you.
The question of how often to feed a baby is one that often arises for new parents. With regard to how often they need feeding, it seems to differ slightly but is generally between two and three hours between feeds. At this stage of their life, any baby is programmed to sleep for short periods and awaken to be fed at such intervals. This is why parents will talk about sleepless nights at the early stage of parenthood. As the child grows older, they will of course begin to go longer between meals, but at an early age, with no ability to articulate their needs nor understand what people are saying, they will find their own way to make things clear to you. This regularity of needing to be fed is why many parents keep the baby in the same bed as them in the early stages.
