Cruise in birth control By JULIE MOULT TOM Cruiseâs pregnant fiancÃ©e Katie Holmes will be reminded to keep her vow of silence during birth â by signs plastered around their home. The couple â following the Scientology tradition of a silent birth â had the posters delivered to their Beverly Hills mansion. The 6ft placards will be placed so Katie can see them in labour. One reads: âBe silent and make all physical movements slow and understandable.â Dawsonâs Creek actress Katie, 26, must âkeep mumâ and will not even be allowed painkillers when she has the coupleâs first child due any day. Friends â believed to be Scientology elders â were pictured carrying the huge white boards through the gates. The âbirthing boardsâ will also tell staff and visitors to stay silent. Followers believe it is traumatic for babies to hear their mother scream or groan when giving birth. They think it can cause âpsychicâ damage, which takes years of therapy to overcome. The cultâs creator, sci-fi writer L. Ron Hubbard, once said: âMaintain silence in the presence of birth to save both the sanity of the mother and child.â The doctrine stresses newborns cannot be poked or prodded for medical tests or spoken to for seven days. Katie began dating Tom, 43, last year. She was well-known for her Catholic beliefs but quickly fell pregnant and is yet to wed.
