Is this wrong of me??

For Christmas my mother in law asked us all to get together the whole family and do photos. But where there are so many of us, it has to be outside. almost in December. and freezing cold. my baby will only be not even 3 weeks old... and i don't feel comfortable keeping her outside taking photos in the cold. I don't know how to tell my MIL sorry but my baby won't be in them. am I being over worried about this ??
