My sister gave birth to a baby. I want to send a blessing message. What should I say? I don't know what to send. If I think it's appropriate, I congratulate your sister on giving birth. You must pay attention to your health, keep a good mood all day, strengthen nutrition, restore health, take good care of yourself and your baby, and let your baby grow up healthily. I will definitely visit you when I have time, because you just gave birth to a baby, so you must pay attention to yourself.
