For those of you with two kids under 2

Hello, so I am pregnant with my first. Lets just say I have always wanted my kids very close in age as I was not one of those kids... My brothers are quiet a few years older than I am. Anyway... How do you ladies feel about having two kids under 2? I would love to get pregnant maybe a year after my first is born but at the same time I feel like it may be overwhelming. I'll be 28 by the time my first is born so waiting a year would push me to 29 and by the time I give birth I would be closer to 30. Do you think the work is too much? Some people say wait till the other kid is out of diapers .. I would like to get some input for you moms who do have 2 kids under 2 for you are experiencing or experienced what I'm curious about.

Thank you !!!
