That was a pretty unexpected twist, I liked it. It came after another, smaller twist, cause I wasn't really expecting the mom cutting onions to be the reason he was crying at all. The dialogue was a bit weird (I don't get how he was being a baby if we look at it as mom cutting onions, as in the vegetable, isn't he supposed to be crying there? What can he do to cry less there? Doesn't really make sense). I think it also could have been a little faster and the art could have had more detail, definitely, because it was pretty slow and not that interesting to look at. I'm also not at all clear on who the characters are and where they are. It just feels like a joke but outside of any setting, which doesn't really work here, I don't know.
Keep it up, just try maybe speeding things up and working on the art a little.
