Most babies’ tummies are normally rounded, especially after a large feed. Between feeds, however, they should feel quite soft and not stick out. If your child’s abdomen feels swollen and hard, or if they have not had a bowel movement for more than one or two days, you should seek medical advice. Most likely the problem is due to wind or constipation, but don’t take chances and seek the advice.
Labor is can be a strenuous time for both mum and baby, and it is possible for babies to be injured during birth, especially when babies are very large. While newborns recover quickly from some of these injuries, others may last for some time. Quite often the injury is a collar bone, which will heal quickly if the arm on that side is kept relatively still. Don’t worry if a small lump forms over the site of the fracture. This is just part of the body’s healing process and is a sign that things are normal.
Muscle weakness in a newborn baby is a common birth injury, caused during labor. However, muscles, usually weakened on one side of the face or one shoulder or arm, generally return to normal after a few weeks. During this time it might be wise to ask advice on how to hold your baby to promote healing or at least prevent aggravation.
Blue Baby Syndrome
Babies sometimes have mildly blue hands and feet, but this may not be a cause for concern. Their hands and feet might turn slightly blue due to the cold, but they should return to normal as soon as they are warm. Occasionally, the face, tongue, and lips may turn a little blue when the newborn is crying hard, but once he becomes calm, his color in these parts of the body should quickly return to normal. However, persistently blue skin coloring, especially with breathing difficulties and feeding difficulties, is a sign that the heart or lungs are not operating properly, and the baby is not getting enough oxygen in the blood. Immediate medical attention is essential.
