Mother In Law

I have a great relationship with my MIL but ever since my husband and I got married she's acted so weird. Saying things like "when you two have kids don't keep them from me" and I don't understand where it's coming from. We've never missed a birthday or holiday and we talk on a regular basis and we also just pop in when we're in the area. I don't know what to say or how to react. My father in law and I have a bad relationship already. (He told my husband I just wanted his money even though I supported him for three months when he had no job and we weren't even married at that point. My husband start a great job and making great money after we were together for three years) but we've never had a good relationship. But me and my MIL always have and I don't want that to change but I'm not going to keep dealing with these rude comments. What should I do?
