What is best in your opinion

Ginny • Hello I'm 25 and loving my life. We are expecting a little boy and I'm in love with this baby.
My boyfriend and I were discussing when to have another baby. He wants them close but this pregnancy was already hard enough that a second is out of the question now. I'd like to wait til our son is out of diapers and helpful with mommy. So what do you think? Have them close or years apart?
