To care for a child with Klinefelter syndrome, be aware of the many ways it can affect the child's life. Babies may take longer to reach milestones such as sitting and walking, due to muscular weakness caused by the disease. Boys around the age of puberty may benefit from counseling, because they are likely to develop slower than their peers and have a less traditionally masculine appearance. They might also have weaker bones and less energy than normal, and they may be somewhat shy. Consider talking to your child's doctor about how testosterone therapy can help with these issues. Boys might also experience learning and language problems, so it is important to work with your child's teachers and possibly a speech and language therapist to help him achieve to the best of his abilities.
