I do not think I have ever researched anything specifically grandparent/grandchild orientated.
I searched quinsy's recently after DGS was diagnosed with it. Searched ebay for sewing machines(and bought one) because DGD would like one for Christmas, I do research presents, but usually know exactly what I am looking for.
Went online to check opening times and buy tickets for Longleat and, once we have agreed the Christmas visit dates, I will go online to buy our usual pantomime tickets. Apart from that, I cannot think of anything else, I do around grandparenting.
