Ignorant in laws

When I was pregnant with my 1st, I stayed with my in laws. They were happy that I was pregnant their 1st grandchild, however they don’t bother caring about my well being. They don’t ask how’s my pregnancy is like, whether I’ve eaten well or not, I just felt like a total stranger in the house. But when my 1st is born, they carry him highly telling everyone that he’s is grandson. I felt so disheartened and taken aback. I felt like without me carrying him for 40 weeks he won’t exist in this world. Now that I’m pregnant my 2nd, I decided to stay with my parents. With my parents I’m well taken care of. Recently we went holiday with my in laws, unfortunately I feel terribly sick. I was not eating well and so worried about my pregnancy, but they don’t even ask about me, at all! I was so sad. All they do is play with my 1st but also never feed and take care of him properly. During the trip I felt so depressed and helpless. Sometimes I don’t know how to react towards them. All I care is about my well being right now. But I just feel overprotective over my kids cause they don’t care about me when I’m pregnant carrying their grandkids. But when they’re born they think they’re the best. Anyone felt the same way as I do? How should you then react? 😔
