We use, for example, \u2018small for gestational age\u2019. For each gestational age we have a normal weight and length of the baby that we should see. We can measure the baby\u2019s bones; so femur length. We can measure the head circumference. We can measure the abdominal circumference and we can calculate whether or not that baby based on those measurements is small for gestational age or appropriate for gestational age or large for gestational age. The small for gestational age baby, we also can describe that with a few different terms and sometimes they\u2019re interchangeable. A baby could be small for gestational age but actually just be on the bell curve for that age and be at the 5<sup>th<\/sup> centile or the 10<sup>th<\/sup> or the 30<sup>th<\/sup> centile as opposed to being an average size baby. So you can have a small healthy, small for gestational age baby. I had four of them because I\u2019m not a big person and my husband isn\u2019t either and they\u2019re all healthy. But if you have a baby that should have been able to grow more than it did but it didn\u2019t, that\u2019s what we would call an intrauterine growth restricted baby. So that baby genetically was predetermined to be bigger than it is. And for example, when we get very poor placental function, the baby can\u2019t grow and that baby would have intrauterine growth restriction. So intrauterine growth retardation actually refers to the baby that is smaller than it should be. And small for gestational age may be an intrauterine growth retarded baby or it may be a completely healthy baby that\u2019s supposed to be six pounds when it\u2019s born.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Large for gestational age babies are babies that are too large and most of the time the large for gestational age baby is due to diabetes. It\u2019s the commonest cause for large for gestational age. There is the baby that\u2019s just big because, you know, dad was a Winnipeg Blue Bomber and they\u2019re just big.&nbsp; Those babies are healthy but large for gestational age and then there\u2019s the baby that is big because it was exposed to too much glucose in utero the whole time. So these babies have; we can actually recognize them on fetal assessment ultrasound; they\u2019ll have a different fat distribution. They\u2019ll have a lot of abdominal fat and fat around the neck and chest.&nbsp; They will be usually over the 95<sup>th<\/sup> centile and some of these babies are like 12, 13 pounds if you leave them in till term.&nbsp; They\u2019re, actually families think they\u2019re really cute but they\u2019re really fat. You can\u2019t see their neck, they\u2019re just. And it\u2019s sad because you\u2019re seeing an obese baby that\u2019s two minutes old. Anyway, that\u2019s the large for gestational age baby that we\u2019re trying to prevent.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>So, there\u2019s a number of definitions we use to describe babies that are too big or too small.
