I'm always on the fence with this family. They come across as dedicated and loving, there's no doubt about it, but the mother certainly does seem to have some sort of issues/addiction to having babies.
I think with all the good intentions in the world, you could never spend enough quality time with each child, it would just be impossible.
Previous episodes has showed a darker side to the family. I remember one of the primary school aged boys commented something on the lines of mummy likes us less the older we get/when a new baby arrives and several of them were determined to never have large families themselves.
In the earlier series it also showed the father locking the younger children in their bedrooms at night time by shutting the door tight and removing the door handles so they couldn't get out. God help them if there was a fire as they were on the top/third floor of the house.
Seeing them burying Alfie was devastating
