In most cases, a card or greeting that conveys a sentiment such as "Congratulations on your new arrival" is an excellent way to share in the joy of new parents. A congratulations card for new parents can also provide an opportunity to offer support and assistance at a time that is sure to bring new stress and questions as the family adjusts to having a new baby.
Pregnancy and childbirth can be difficult, especially for first time parents, and there are many concerns about the health of a newborn leading up to his or her birth. Because of this, congratulations for new parents might also often include language that reflects happiness about the "safe" or "healthy" arrival of the new family member.
In addition to a card and a gift for the baby, many people also find small ways to help out new parents, such as making large meals and freezing them for when the parents are not able to cook. Additionally, some people might offer to run errands, perform household tasks, and take care of pets or older siblings. This can help ease the burden on new parents and allow them to enjoy spending more time with their new infant.
