If the fetus has hands and feet developed enough to actually look like hands and feet, getting handprints and footprints is easier nowadays. You don't have to put ink on them. They have these things that are like a cardboard photo frame, instead off glass there are three windows of thin plastic with ink only one side, one for each foot, and the third is for the mom's thumbprint ( for the term babies hospital birth certificate which really isn't jack shit as legal birth certificates come from the state, they are more for keepsakes) )You put the ink side facing the paper and the gently press the litte hand/foot onto the side without ink, it doesn't take much pressure, but it smears easily and is hard to get all fingers and. toes so usually takes a few tries. You do have to handle them gently as the skin is very thin, similar to pinky mice or newborn hamsters if you have ever seen those.
Regarding fat babies, infant's of mothers who develop gestational diabetes are usually large. The gestational diabetes can usually be controlled with a strict diet, but sometimes insulin may be required. Some pregnant women are not complaint, so the more out of control the mother's blood sugar, the bigger the baby. They are often so big that they have to be delivered by c section as much as a month early After birth you have a huge fat baby, it that cannot keep up their own blood sugar. pumas they are used to being exposed to high sugar levels from the mom, requiring IV dextrose for several days, they may need oxygen, or a feeding tube also, while they are bigger than the babies in the normal newborn nursery, they are still premature and therefore immature, If the mother was really bad at not caring about her diet, the baby can have several diabetic type neuropathies, and even brain damage, usually this is only the extreme cases, and all because the mother did not give a shit to even bother to try to to control it, and so sad because it is very damaging to an infant that otherwise would have been normal.
On the subject of the colors of the very early pre term deliveries, and late term miscarriages, the infants (26 weeks and under) are usually a very dark red, the term to describe that color is plethoric. If the fetus has died, they will have areas that turn a dark purple, then black depending on how long they have been dead, if dead inside the mother a long time, they look really bad, it's called maceration ( starting to rot before being expelled) this can be pretty grim to see in an older more developed fetus.
They can have the white color that was pictured if the placenta detached and was expelled before the fetus and the fetus has little blood in the body, and also after death. When a fetus or infant that has passed is left in one position like, on the back face up, they start to look paler on the front because blood pools downwards, due to gravity, ( liver mortis) if you were to turn them over you would see the red, purple, and black coloring there more.
