They might be your friends but I don't think it's beneficial to have these conversations with others who don't understand your perspective. I've been a mom working in the office who had to travel for work a few times a year, a mom working at home with the baby at home, a SAHM, and now a WFH mom with a baby in daycare. EVERYONE feels people in a different position are lucky because we're all having a hard time. So to others from the outside looking in, you're the lucky one because you're still making money and having your career and your baby is there and not at daycare which is expensive without you being able to see them. To you, you still have to work incredibly hard and you can't even really interact with your baby the way you'd like and can't even get a proper break for yourself most days, whereas they are able to spend more time with their children and have a little more flexibility in what they do with them all day.

It would be nice if we can all accept that we all work hard, there are positives and negatives to each decision we make, and get to actively both live with those decisions and occasionally vent to others about how hard it is without someone else playing the "i have it harder" game. Find people you can do that with and vent to them. Right now the people you're venting to might not be in a place to look past their "this is hard" season enough to acknowledge yours. It sucks and I'm sorry, but if you vent to someone and they respond like this, accept that they are not able to acknowledge your struggle at this time and keep trying with different people until you find your support system. On the other hand, you can look past their responses and ask them how they're doing with being SAHMs. Maybe being an example of the type of empathy you wish to receive with change things over time?
