Hi , my sister-in-law has often asked me to pick up or babysit her child/children . Yet has only once returned the favour . Also she is quite deaf and a bit of a tidy freak so prefers housework to childcare so I am not that keen to have her babysit my lot anyway . How do you tell her she is abusing the connection without being ungracious . I often try to fob her off with excuses but I really wish she wouldn't ask anymore .
