Did they reallly do that many chores and childcare? I cannot remember anything exceptional except being hauled out of school in Triplets.
It is mentioned quite often especially in the later holiday books the amount of helping out the trips do. In Richenda, they automatically make plans to look after the younger kids and Charles even turns to Len instead of his parents when he wakes up feeling ill in Joey and Co in Tyrol.
So it would make sense that if the Trips did go home every day they would be expected to help out in the afternoon/evening until the younger kids are in bed, and only then could they do their homework.
But surely in Richenda they helped out with the younger kids because Joey was ill and it was much the same in Joey & Co. Charles went to Len because they had been told not to worry Joey. Unfair I know.
Len could ,and maybe should, have gone to Anna for help.
When Joey first went to Switzerland she actually had quite a lot of help. She had the Coadjutor for the baby twins and Beth Chester for Charles and Michael. Stephen was at school.
I don't know how it would have panned out later on but she might have had more help if the older childen lived at home.
I don't think the triplets were ever given more to do than the Bettany girls might have done in the same circumstances.
I do think it was unfair that Len had to come to Joey's rescue in Joey & Co when Joey keels over. I cannot remember though if that was just Len or the other two triplets as well. Probably the three of them.
Joey's fainting was probably as a result of Michael's escapade on top of having given birth to twins fairly recently.
It was ridiculous Jo having 11 children when she could not really cope with that many. The youngest twins should have been ditched and perhaps Felix who always strikes me only as a slightly cleverer version of Mike. I think six or seven would have been a better number. My opinion only though!
