Hi Jan!
Well obviously I can't tell you how I feel after number 2 yet LOL
But we are going to aim for #2 to arrive when DD is 2.5-3 years old (so starting TTC early next year and hope my body cooperates!). It will be roughly the same age gap between myself and my brother and we have always been super close. I am really enjoying working part time as well and want to continue for another year or so and also we want to be settled into a new house before #2 arrives. So it is different for everyone but I guess just go with your gut feeling hun and it will all be so wonderful no matter when your new addition arrives!
