OK, what does your licensure status have to do with the post and the information you replied with? Just saying I'm a mom with twins means a lot more to me in regards to this post?
I just find it funny how, on the dis, people love to say "I'm an RN". Just say it if it really pertains to what you are writing about!!
And to the OP - I think that you are perfectly capable of taking care of your childs ears with or without an RN license. Tell your SIL that she doesn't need to groom your children and tell your hubby that he needs to verbalize his concerns when stuff like this happens (if he really has them - or just said he did when he saw you flip). And there would be no way in hell that I'd let my kids go back to SIL or MIL house without me.
I used my status as an RN because it is actually is very relevant. My sister in law knows that I'm a nurse. Why would she apply a "medication" to my child without first consulting me, knowing my background in healthcare. It was not an emergency situation. Sure anybody can take care of their child's ear (under the care of their pediatrician of course), it was more about her. She's using it like, I don't know what I'm doing "look she's a nurse and she can't even clean her own kids ears what do her patients look like". That's how she makes me feel....


. I would have called them ALL on their stuff and that would have been the end of that mess. The reason they keeping doing things is because no one seems to have stepped up and corrected their behavior. I'm sorry but if your DH was not in agreement, he should have stated so, all he did was show that he will allow them to do ANYTHING to YOUR children and that because it's family it makes it okay. I would tell them that if they were not able to keep their hands to themselves and stop criticizing how I did x,y,z, they were no longer welcome to visit or have my children visit them till they got it under control.

Just saying..........
