During the English sessions a parent/carer is at home too, but for babysitting I am the sole responsible carer. I make this distinction because I cannot be a responsible carer if there is a language barrier. Whether I offer English-speaking babysitting depends on your child’s language level and e.g. parents’ language.
During my English sessions the focus is on language and language learning rather than simply communication by any means necessary as it is with babysitting. If you have any more questions about this, feel free to ask!
