Consider a situaltion: an adult child has her/his own chidlren needing childcare. This adult child regularly gets assistance from her/his parents in form of granparental childcare. Do you know any empirical studies about intra-familial payment for grandparental assistance (compensation, monetary reward for childcare)?

I have found some information, e.g. in Folk (1994) or in Wheelock and Jones (2002), but I am particulary interested in contemporary European statistics (especially, Germany).

I would be very thankful for your help!
