Insensitive parents in law!

Mmm
I need to rant. My mother in law acts like she doesn't understand pregnancy. She doesn't understand why I need to avoid certain foods. After all, her son turned out fine when she had them. And she thinks I'm overly cautious on the food I eat. So what if I do not want to have those foods?? I'm not starving myself, neither do I enjoy it if I think there's a possibility it's bad for my baby. 
Also I was really sleepy that evening. And she said: "how are you going to feed your baby at night if you need to sleep so much?" Does she not know women get tired easily in their first trimester. Of all people I expect empathy from family and fellow mothers but sadly that isn't the case
