How does anyone have more than one kid

I have a 2 month old and I honestly for the life of me cannot figure out how moms do this with a toddler, even 2??? At home. I can’t do anything anymore, it’s a miracle if i can clean the house a bit or cook dinner. I dont even work. Am i just doing this wrong? My husband wants a second kid again soon and I literally cannot even fathom having two small people in need of me while taking care of the house and not falling apart myself
