 So the first year of a child's life is a time of exceptional growth. From the moment they're born to about four to six months, a baby normally doubles their birth weight. And it is quite normal also for the baby to lose weight just after birth because they are born with a lot of extra fluid. So it's very normal for a baby to sort of lose a little bit of weight in the few days after birth and then gain them back quite quickly and then by four to six months depending on whether they're breastfed or formula fed, they will have doubled their birth weight. And by the 12 months or by one year they will have actually tripled their birth weight. So that is really exceptionally fast growth, accelerated growth in the first year. They also grow taller and heavier as well each year. And sometimes it's, you know, if a child gains more weight in proportion to their height, you could look at it as maybe the fact that they're maybe overeating or they're not exercising enough, they're not as active. And inversely again, if a child doesn't gain enough weight in the first year compared to their height or throughout their childhood that it could also be due to malnourishment. But one of the things, it's not only just in height and weight that the baby grows or the child grows, they also, there's also a lot of physical changes in the childhood that are during childhood that are happening. Things like brain development. The baby will, the child will start to begin, develop their cognitive abilities. They'll start to develop their language skills. They'll start to develop any emotional, emotions and also social development as they get older. The nerves also will grow longer dendrites and axins. So the nerve cells actually multiply dramatically during that time as well to create more connections as well. There's exceptional growth in bone mass and muscle mass and bone density. And also their organs will continue developing. So especially things like reproductive organs, they continue developing until sort of adolescence and adulthood. But a lot of the organs already existing are remarkably similar to the adults in terms of their structure. But we've seen as before that some of them are still immature. They have immature kidneys. So we don't want to include lots of protein and lots of high salt in their diet when you're weaning. We know that their GI tract is still developing as a child. And it normally takes, even the microbiome, takes about two years to grow, to fully establish. And then the reproductive organs are still growing and developing throughout childhood. So it's a really exceptional time of growth, development, and it needs to be supported with the right nutrition.
