The reason for this is the following：

1, safe for pregnant women

There were many guests at the wedding, and the scene was very noisy. When pregnant women are pregnant, they need to pay attention to various safety issues. In the busy wedding scene, it is likely to be accidentally hit, affecting the safety of pregnant women.

2. Wedding food

The food at the wedding banquet is very rich, most of which are greasy. During pregnancy, pregnant women should avoid eating. Some foods are not fit to eat. If pregnant women eat inappropriate food at the wedding reception, it is not worth it.

3. Noisy sounds

Music or firecrackers are usually played at the wedding scene, which is loud and harmful to the fetus. Pregnant women need a quiet environment and are not suitable for going to noisy places, so pregnant women can't attend weddings in many places.

4, poor air circulation, pregnant women are prone to dizziness.

The wedding scene is usually crowded with people, and there are still smokers in it. If it is summer, the air circulation is even worse. If pregnant women are in such an environment, they may feel poor breathing and dizziness. In addition, pregnant women can't breathe fresh air, and the fetus is prone to hypoxia. Moreover, second-hand smoke is also very harmful to pregnant women and fetuses, so pregnant women rarely appear in such occasions.

5, there are many people and many things, and pregnant women are easily hit.

There will be many people at the wedding scene, with many tables and chairs, drinks, decorations and so on, and the furnishings are complicated. It is not convenient for pregnant women to walk around, especially in the late pregnancy, when their stomachs are big, they will trip if they are not careful. Moreover, there are many children at the wedding, so it is easy to run around and bump into pregnant women.
