How did you handle your mother in law, when it came to kids/kid talk?

How did you handle your mother in law when it came to kids? I have been married to my husband 7 years, we are waiting about 2 more years before we have kids. Long story short I was in a car accident 2 yrs this August, I lost my job as I needed to re learn how to walk and my in laws were awesome and made an apt for us on their property to help with finances. The settlement is slowly closing, but we feel it will be closed the end of this year or beginning of next. So both my husband and I have agreed that 29-30 (26 now) sounds about right to try and have children, as we want to get settled in a house and travel and get horses and just enjoy 1 year stress free life from bills and such.. Well my mother in law knows all this as well, but recently she has been being annoying and commenting about how she has the crib, car seat and toys and such, that all she needs is the baby.. I have commented that we will do all of that once we get a house and we get the things we want to do our of our systems, she then commented with "forget the horse and have a kid already." I was shocked, as I could tell she wasn't joking. I tried to speak to my husband and he says I am just looking into things to much...but not more than an hour later did she "jokingly comment" So do you leave your Birth Control Pills at home? As she was saying she was joking, that she was going to change them to sugar pills so I get pregnant...I am terrified to have children a little bit because of her. I mean I don't even have a kid and she is already trying to run my life, imagine my child's life?! I mean how do you handle this stuff? because I have tried to speak to her before about something that angered me a few years ago and she went off crying to everyone that I was being so mean to her and such and everyone was mad at me. I mean I am trying not to get worked up over this, but I want all this stuff handled before I get pregnant and have a child...so what did you do? if you had any issues like this?
