DW and I were trying to recall - have they ever had a mother on real BB? Know there have been some on the sleb version (e.g. Melinda Norks, Anne Diamond etc). And some dads over the years.
Interesting to note the changing role of Davina - when it started in 2000 she was a contemporary of the contestants, v. much seen as a "mate" figure - now she is 7 years older and they are all on average 10 years younger, she is now a "mother hen".
So many of the contestants just seem like squabbling children - that's why we've given up with it.
