Two kids born in the same month?

I have been trying to plan my second pregnancy since I work for a school that way I would have more time at home with the new baby in the summer. The main issue is it took is 3 years to get pregnant the first time and I know I have the best odds of getting pregnant during this first ovulation. My concern is that it would put my due date almost the same week as my current child. I dont want him to not feel special or important (he will be turning 3 in April). Do you have more than one kid that close together? If so how does it work for your family?!?
