Be honest, am I in the wrong? MIL complications -long story sorry!❤️

My MIL has been overbearing and over opinionated since bub was born. We had a great relationship before, but due to birth and health complications with bub, she’s started rubbing me the wrong way. She’s in the medical field and often chimes in when not asked and we see her every other weekend. All convos end up critiquing or offering “helpful insight” on my parenting. I took the step to distance myself, so bub and I get out more and limit interaction to only once a month really to keep a bond with them and bub and my husband. They have a family member in the hospital with cancer for over two weeks, so I have been offering to support them, dropping gifts at the hospital, checking on their pets and such since I know it’s a huge thing to go through. However, it’s been a couple months of healthy distance and I find it’s made a more positive relationship for us. Our babe is now sick with a nasty cough and loud breathing and is 6 months old. He has past health issues so since it was the weekend, I asked my husband if he thought we should send his mom a video of his breathing to see if she has other suggestions for what we could do to give relief before going to the doctor today. I left communications to him to keep it easier. I ended up getting a phone call from her, telling me he needs to go to the ER like yesterday…and that I need to go to the closest ER even if it’s shitty because they have oxygen and they will rush babe and I in an ambulance to the better hospital but at least he’d be on oxygen because he looks like he’s barely breathing…and is either pneumonia or RSV. I asked to wait 10 until hubby gets home and she told me no, and that the 10 mins could be life or death…and that he should have went in yesterday. Cue mom guilt with ppa Hubby meets me at the hospital, we’re there for 3 hours, still waiting…they tell us it’s a 6 hour wait…the nurse didn’t seem super concerned about him so we left. I stayed up all night monitoring him and got in with our fam doctor first thing since she’s a literal saint and keeps an extra eye on our son with his previous complications. She did a super thorough check, it literally was just a virus, like we thought, and she said that if he had either of those he wouldn’t breastfeed, and wouldn’t be as happy as he is. So we returned home. I let my hubby know since he’s working. He tells me he feels bad since we spent hours dragging our poor little guy around when he could have been resting. He let his mom know and she said “well I know he wouldn’t be feeding if he was sick like that, she didn’t give me enough information”. I literally information dumped everything so she knew since she called me. I told him it’s totally fine I know she has a lot on her plate, it just sucks it escalated to telling me my son was going to die if I didn’t get there fast enough… So he just told me “well then don’t ask my mom again” when I ran it by him and had him initiate the convo because I’m a FTM with anxiety trying to navigate awkward relationships. I won’t be asking for insight again, I’ll stick to telehealth after hours and my fam doctor. But am I a jerk for being upset? I keep it to myself because again I was the one thinking we needed insight. But I’m just kind of shocked that at first I was shamed for not going sooner…and then it was spun onto me saying I hid information from her when I told her everything…so it’s like she didn’t want her son to know she was wrong which we totally don’t care like nobody is perfect, just a little “sorry hun, just wanted to be extra cautious” or something would totally be fine with me. Sorry for the rant I just have nobody else to run it by 🤦🏼‍♀️
