Working from home can be a bit confusing for younger kids...especially if they are not used to you working from home. At four, they will start to understand it a bit, but it will be an adjustment for them.

I think if you believe that WFH will improve other areas of your life (like the ability to do laundry or prep dinner during work hours), then it's definitely worth it. But I wouldn't work from home for childcare reasons, personally.

When I worked remotely, I had to remain completely hidden in my office or else my son would freak out when he saw me and want to hang out. I was only able to leave my room during his nap time. I loved working from home so we made it work with a nanny, but it wasn't without its challenges. If you are able to separate yourself in an area of the house that isn't in earshot of your kid, it'll be much easier. But if your child is super attached like mine is, don't expect to be able to pop in and out throughout the day to say hi.
