Looking for people's experiences on having a second child when there was no "baby fever."

Background: My husband and I always agreed that we wanted two children. My DD is going to be 2yrs next month and DH is so ready to have a second.

DD was an incredibly easy baby but she is a very strong willed toddler. I am exhausted and stretched thin. DH and I both work full time at very demanding jobs. We see our DD about 2 hours a day and on the weekends (we have a nanny). I love her more than anything but definitely do not feel like something is missing from our family being complete. However, DD LOVES other children, especially "babies." We can tell she would love having a younger sibling.

DH wants to have another child and I just don't feel compelled at all. I don't want to be pregnant again. I don't want to deal with all the postpartum misery. I don't want to do the whole baby thing again when our DD is finally learning some independence, giving us some back some freedom in our everyday life. Don't even get me started on the financial implications of childcare for two children.

When I ask DH why he wants another child, he says so DD has a sibling and because he loves her so much.

So I guess I'm looking for people's experiences of having a second child when they weren't 100% on board or didn't have any sort of baby fever.
