Yes dear. If a mother is stressed during pregnancy her child could have serious physical and mental problems. Pregnant mothers should take good care of themselves. Eat a good diet, do some meditation and prayanama, watch comedy movies and laugh since it is good for health! Also put light some yagna incense which is natural and creates a good calming environment.
Eat healthy — A well-balanced diet can help reduce stress, as well as keeping you and your baby healthy. Exercise — Thirty minutes of mild to moderate exercise several days a week is enormously beneficial. It can also help lower cortisol levels, which is the hormone that causes anxiety.
