Pregnancy can only e announced at the 12th week.
It is customary to announce an addition to the family only after 12 weeks. However, Kate Middleton became an exception due to severe toxicosis during pregnancy. Her family had to explain the reason for her absence at official events.
There is a very strict rule regarding children’s clothes: pants can be worn by adults only. That’s why children wear only shorts, regardless of the time of the year. This dress code should be followed up to the age of 8.
