When my older son was little, my mother in law, who lived far away from us, and whom we saw maybe twice a year, sent lots of gifts for him throughout the year. She was an avid yard sale shopper, so she often sent boxes of toys and clothes for him. My husband and I wondered from time to time if we should try to dissuade her or ask her not to send so many noisy, busy toys. We never did though, because her love language was gift giving, and because we lived so far apart, we knew this was her way of feeling close.
When my son was almost 5, my mother in law passed away from cancer. We are so glad we never said anything about her excessive gifts, but simply let the two of them enjoy the short relationship they ended up having.
