How to get grandparents more involved?

My husband and I have 10 month old baby. Both my parents and my husband's parents live overseas and we never see them. We are in touch though through email, telephone and we constantly send them photos of their granddaughter. They have other grandchildren living near them and they spoil them with babysitting, gifts, celebrations... We feel our daughter is left out. They never remember to send something for her for holidays but they do buy things online for themselves and other grandchildren and have them shipped to our address so we can bring it to them when we visit. I feel really hurt when I get shipment full of baby stuff for their grandchildren in South America (which I have a responsibility of bringing to them) but nothing is for our little baby. How can I make them more involved? They always say how much they love our daughter but they don't show it. I don't want to offend them and I know helping is totally optional for them but it's also optional for their other grandchildren and they still do it. And btw, my husband and I are in worse situation financially compare to my nieces and nephews.
