No two children are the same and nor do they have exactly the same needs. They are all individuals, and when a new human being comes into the world, we have to get to know that particular person. At first, it can be difficult to interpret all the signals a baby is sending out, but little by little it gets easier. Sometimes the signals have to do with being thirsty and hungry, but a baby may want something completely different. It is important to realize that no babies behave exactly as the various books say they should.
All babies are different.
Babies do not need anything other than breast milk or formula milk for the first four months of life. Food other than milk is unnecessary and can be damaging at that age. If a mother is unsure whether her breast-fed child is getting enough milk, she should ask her health visitor to to check whether the baby is growing. If not, it may be necessary to feed the baby more often. Nursing mothers should use both breasts to stimulate their milk production.
