From what I have read, Colin Caffell has remarried and has a daughter. I think it is clear that he cared for the twins very well...whatever his "artistic temperament. I am pretty chaotic due to my dyspraxia but my son remains well cared for.
I don't think we can say that the twins had a chaotic life with Colin....it seems that Sheila's mental health caused problems but she was being treated for this.
I know little about the bruising that the twins had <goes off to read more>
Neverthless,Droosie,,those little boys would have been frought with confusion.Mummy " being funny ",,as children that age have no real concept of illness or what can happen and they may have seen Sheila as a source of amusement at times.
Then Daddy with " this lady " who wasn't their mummy. Their stays at WHF,,under sufference from poor Junes' religious mania. The different child-minders,foster parents and social-workers.
I bet those kids never knew where they'd end up from one week to another. When they were just with their mother,,they were getting themselves ready for school,,,washing,dressing and also breakfasts,,and turning up at school looking tired ,pale and dishevelled. This would have been the time that the teacher contacted the health nurse,or social worker to see what the problem was.
This only happened when the boys were living with their mother. I don't quite know how they arrived,or got to school. Poor little mites. Sheila had completely lost interest because of her deteriorating illness.
