New baby

First night home with my newborn, it's been crazy especially with an 18 month old boy on top of it all, but really, what gets me is that I asked my SO to keep up with the house while I was in the hospital. He said he did. Well we walked in tonight and it's an absolute mess. So here I am cleaning, trying to take care of my newborn and toodler so he starts dinner and then disappears. The stuff on the oven is burning so I go finish it while keeping my toodler away from the baby (he doesnt understand how to be easy with him yet). Newborn wont stop crying so I feed him really quick, while my toodler rubs around like a crazy person. He cries when he's done and I start crying. Eventually he falls asleep so I lay him down get my toodler plate and then sit him in the high chair, get my plate set it down and our cat came out of nowhere and helped herself to my bowl, at this point I really just cant stop the tears. My SO is outside messing around with his motorcycle. Has come in and out and completely ignored everything and went right back out. I'm stressing out big time. I just needed to get that out some way. 😕
