Woo Hoo!! I'm so happy for you!!!
schooling with an infant is pretty easy, imo-because my infants were usually attached to me (either literally because they were nursing or because I was carrying them in my sling!) so they just did what I did. Plus it kept them "safe" from big brothers to be in my arms...

They also napped longer, making it easier to do something constructive during that time.
Plus in the first few months they are still a novelty so the bigger ones will jump at the chance to help with the baby. By about six months that seems to wear off...

at least in my house it did!
I'm so happy for you!!! I would do cartwheels but I can't, so I'll just keep grinning away!!
