Mother in law situation ?

So note we live RIGHT BESIDE my father in law and mother in law.. I have a 9 month old. Anyways.. my mil makes the simplest things so difficult. Anytime I ask her for help she beats all around the bush and it’s fine if you don’t want to help me but just tell me. If you can’t go to Walmart with me and my 9 month old and I’m 7 months pregnant all you have to do is tell me, I ask because I’m just so tired sometimes.. I’ll literally ask her to go to Walmart and she will make up an excuse and then later during the day she will go to Walmart. And then she gets mad at me and won’t talk to me for days on in even though we live next door. Like if I want them to see my daughter, I have to bring her over there.. they never come over to see her. They haven’t seen her for a week now.. and like I said, we live next door. It bothers me so much. Should I be bothered? Or am I overreacting or what?
