First day alone as mom of 2 fail...

Its the first Entire day alone with both boys since my husband went back to work and I had it all planned where I would feed the newborn before my eldest who is 14 months old got up and then feed him and just have the day staggered... whelp nope. They both woke at the same time and my old was covered in pee from peeing out his diaper which rarely ever happens... so had to bathe him while the newborn screamed and cried in his chair/safe spot. Fast forward and had them both fed and usually the newborn is great about laying and napping in his pack n play so I can play with my oldest nope.. it was the morning he did not want to be put down and my oldest was flipping out and this continues until his nap... he always naps 2-3 hours but not todayyyy. He napped 1 hour. I was in the middle of feeding the youngest and the oldest was flipping out and this continues until his second nap. (Thank goodness for that) oh and I forgot to mention my oldest takes a huge poop and pitches a bloody fit when I try to change him and he’s thrashing around to get away on the floor which never happens until now apparently and gets it all over the rug... oh joy! and then I’m feeding the oldest dinner and the newborn is losing his mind wanting to eat so finally get to feed him and what happens... his violent projectile vomits his entire bottle all over us both. I sit the bottle down and can’t bath him at this time so make the best of the situation with changing clothes & cleaning up and come back to my oldest drinking his bottle 🤦🏼‍♀️. It has been a nightmare and the day isn’t over.... I don’t think I’m cut out for this mom life. I just want to cry.
