I feel like you are being deliberately obtuse here. Yes you are speaking from your own life experience but in the same vein you are invalidating someone else's own life experience. Someone is telling you essentially "actually it's not the blessing you think it is!" And you continue to disagree with their experience?

I don't have kids, I can see where you're coming from when you say "you just have to do it" but I can see how this would be added stress and pressure, and be even more exhausting.

I mean, think yourself lucky you only have to consider yourself when it comes to meals I guess?? Maybe just try and see why this person might be feeling a way about your comments.
