you need to sit down with her and your mom and just explain how you feel and have your mom explain to her how much she loves her and that she would love to get to know her kids and would love to have them around and explain that she is close to you and your daughter because you guys have been around longer. make her feel real comfortable and maybe you guys could both invite her over a couple times a week and her kids and do things such as going out to eat, to the park, etc. also make sure your mom has some alone time with your sister and her kids and also it is important for you to have alone time with her also. she just needs to be reassured and even if you have to go alittle bit out of your way to do it and if your mom has to do the same its just until she gets comfortable and until you guys get to know her kids better then I am sure things will get better and you guys wont have to try so hard. also when your child is around and your sisters kids are around try to make sure your mom treats them all equallly and not to give your child to much attention, even though it might not happen without her realizing it just because she has been around her longer, but especially in the beg. you dont want your sister to feel like "see i was right my mom does give more attention to her than my own kids"
maybe plan a vacation someplace just you guys your mom and kids, no dads, husbands, or whatever.
good luck
