In-laws are what I'd describe as fair weather, flashy grandparents, e.g they live 40 mins away but only see our dc every 2-3 months usually when we instigate it. Theres lots of 'gushing' & presents involved... Now they've asked to just have the eldest (4) for a couple of nights, so they can spend 'quality time' with them..which I guess is an advancement but I can't help but think they should have both children else it'll appear like favouritism & leaves us explaining...& also not particularly benefitting from a break!
