Dealings with your mother-in-law are the territory of your husband. He seems completely untroubled by his mother's extra time with his sister and their kids, and you should follow his lead. You don't explain it here, but perhaps your sister-in-law and her family are in the kind of financial straits that your family fortunately is not. So Grandma does something extra for this brood that yours does not need. You seems to have no other complaints about your mother-in-law and say she's an excellent grandmother to your children. Leave this alone. An important lesson for children to learn is that fairness does not dictate exact equality. If they find out about about Grandma's special visit, you just shrug it off and point out some wonderful things in their lives that their cousins don't have. If you want your children to have more time with your mother-in-law then faciliate that -- just don't make it about material possessions.
