Having two kids under age two?

Who has two kids under two? Is it tough in the sense of it being down right overwhelming? Or is it not as bad as it seems?

My husband and I have two kids. One 4 years old and the other 9 months. He really wants to have another baby and I would love too, but since I don't know what it's like having them so close in age, the thought is kind of scary. My youngest is also still ebf and super clingy, so I feel like jealousy would more than likely be an issue. Can anyone give some input and share your experiences?
