December baby pains

So I have thee children. Ages are 7,6 &3. My youngest two have birthday in December the 4th and 20th their father( my love) birthday is the 17th.
I really want a baby and he has agreed to give me another but there is a freaking catch. He wants to conceive in march to have yet again another December baby. 😩😩😩 I'm really dying here because all these birthdays plus Christmas are just waaaayyyyy too much for me. 
I know we all want babies but would you rather conceive a baby now or next month to give birth in October or November?
Or am I just overreacting?
**just in case anyone gets offended**
We suffered the loss of a child and during that process it almost cost me my life. I know having a child is a true blessing I just don't want to overload myself or him when it comes down to the holidays.
