I have a few frineds with ther birthdays near christmas and they always have said that they only get 1 present from family for a combined one. I personally always buy them seperate presesnts as my thought is they give me a birthday prsesnt in march and a christmas present in december so why shoudlnt they get 2 pressies!

I have said to DH if we ever have a baby in december we will make a big thing of birthday also.
