I have a 6yo, a 4yo (17 months apart) and a newborn. If I could go back, I'd wait a little longer before having the second baby. I went directly from nursing to being pregnant again to having another baby. I feel like I didn't get a chance to really enjoy either my first being a toddler, or my second being a newborn. I love, love, LOVE that the girls are older now that I have a newborn again. I feel like I really get to enjoy him being a baby. I do have to say it was somewhat a shock to the system to have a newborn again since it has been so long, but I wouldn't change that.
