I have a GD (who just turned 9 y/o last Sunday) and lives with my eldest son. My younger son and D-I-L also have a 7 1/2 month old son. I've taken my GD to San Antonio alone for a week (when she was 7 y/o) and took her to WDW this past January. A month or two before we left, I decided to include her dad in the WDW trip, so now plan on taking her back to WDW next spring on a trip for just the two of us. I took my younger son and D-I-L to WDW Sept 17th-24th, but they did not want to take the baby, so left him at home with his other grandparents. I don't want to make a difference in the two grandkids, but know there is no way I can include the 7 month old in the spring trip, as then my GD wouldn't get to ride the rides she wants, plus the 7 month old is really too young for me to take that far by myself. However I have a D-I-L, who is rather jealous of my GD (even though she loves her dearly) and seems to resent my trips with my GD. She has started reminding me that I'll be needing to take Logan on trips too and has even suggested I wait to take my GD back, until Logan is able to go. She says maybe when he is about 4 y/o, but my son says about 7 or 8 y/o, so he'll remember it. However, I feel it would not be fair for me to make my GD wait another 4-7 years to go back, plus at 13 y/o-16 y/o she probably would not want to spend a vacation with her GM and little cousin. I know we'll be taking several more trips, before my GS is old enough to go with me and even then because of their age difference I'll be taking them seperately. How do other grandparents handle this? or for that matter those of you who have nieces or nephews significantly older or younger than your kids, how do your parents handle it and what are your feelings on it?
