I had this issue with my inlaws. They didn't understand our rules, and our boundaries. In fact they tried to tell us the rules we were going to change. That conversation did not go over well. They learned that our rules are to be followed if they want to see their new family member. To put it in to perspective, my sister in law knows I am a CHL holder. I was at the great grandparent in laws home. My sister in law asked for the keys to go get the diaper bag, and I didn't think anything of it. She came back in the house screaming where is it. My response of course "where is what?". She said "your gun, I know you have one on you." Well of course I had one with me, I never travel without it. However it was locked in the safe in the vehicle which she failed to find. She said she had thoroughly gone through our vehicle to find it, and that I was a threat to the house and the child with a gun on me. Now my son wasn't even walking at this point, and crawling was still a challenge. I calmly explained to her, that she is not welcome in my house, that going through my vehicle looking for a weapon is a good way to get hurt, and she is not allowed around my son. I took my son, and walked the great grandmother out to the vehicle to show her it had been locked in the safe, in the vehicle the entire time. I explained that we won't be coming around while she is around, but we will when she is gone. That our rules are to be followed, and respected, which includes how we choose to raise our son.
That seemed to end most of the issues we had with each other. But keep in mind, in laws can be crazy, and you need to make it known you have boundaries and rules. Those rules are followed or you don't come around.
