Should I quit before my maternity leave ends?

You’re not exaggerating at all. It’s easy for people to talk when they’re not the ones going through it. I would’ve done the same thing, and I actually did. My daughter didn’t get that seriously sick, but I quit my job to be able to take better care of her.
I can imagine how horrible and scary that experience must have been. My daughter got RSV when she was only 2 months old, and we spent a day in the hospital. It was one of the worst days of my life.
I can totally understand you. Just do whatever makes you feel better. ❤️

If you would be willing / able to quit your job, is there no way you could just extend your leave a bit? Give him time to fully recover. I am not saying you are overreacting, because what a horrendous thing for you both to go through. It must have been awful. But he will hopefully be completely fine soon and is not going to need extra care or anything because of his RSV. So whilst wanting to be close to your baby for longer is a completely normal reaction, I dont think you should quit (unless you can financially afford not to work for a long time). X

You can get FMLA! no need to quit your job and they cannot fire you for FMLA.

If you WANT to quit so you can be a SAHM, I say do it. But make sure your family is in a position to do so, and that you and hubby have the same view of what is expected between both if you do so.

Mine didn't go through anything like that and I still quit. I didn't put my first into daycare and refused to do with my second. My first is also suspected asd and between a new sibling and the start of a new school year it was a lot of changes for him and that can trigger meltdowns so we needed someone available to get him from school at the drop of a hat. You do what is right for you and yours. Fuck anyone else's opinion.
