This may be long, so bear with... DH has cousin in another European country who has a DD aged nearly 12. Cousin's family bit dysfunctional and the DD not very well cared for - nothing specific, more just a general lack of care/concern for her well-being. The DD's grandmother (ie my DH's aunt) comes over each year to visit her own mother for 10 days or so - the aunt's mother is quite protective of her time with her daughter (the aunt) and pretty much insists on having her to herself, ie without the grand-daughter, for pretty much all of the visit. For the last two years, the aunt has brought her grand-daughter over who has come to stay with us for a few days as my DD (other girl's 2nd cousin) is similar age. The first year was fine, the girls got on very well and were together for most of the October half-term. Last year was also fine but as my DD had just started secondary school, I asked if we make the visit slightly shorter - this was OK, although I am aware that it did then cause a few logistical problems since the 2nd cousin had to be got to and from me and other family members had her with them for a few days due to the aunt's mother's insistence on being alone with her daughter for most of the trip.
Hope you are still with me, nearly at the point of all this..
Anyway, I have now been asked if we could do the same this year and if so, how much time we could have the other girl. Because of other commitments and my own DD's wish to see other friends (language barrier means that other girl not good in a group), I have said 3 days/3 nights is what we can manage. I was aware as I said this that it does cause a logistical problem and leaves the other girl "floating round" various family members - the grandmother has now said that that causes too many difficulties and is not going to bring the other girl at all. My question is am I being mean to a little girl who needs a bit of care and concern, or is my offer reasonable and it's then up to the girl's grandmother to make a decision?
