my cousin (the first of our generation to give birth in our extended family) also set out a decree that no one was to give gifts to her then unborn child, although she was due in january. she said christmas was about her, not about someone who wasn't even born, yet. if i remember correctly, she was hurting a month later when she didn't have anything for the baby.
my own bad reaction: i was 12. the oldest sibling in my family, i had a 10year old brother, an 8year old brother, and a 6year old sister. i was already getting a head start on being an overly dramatic, emotional teen. mom handed me my christmas present (in my family, we open one gift at a time so we can see what the others get), and when i opened it.... inside was a training bra. i was MORTIFIED. i ran from the room and refused to spend another minute 'with those people' (meaning my parents, i assume). i don't know mom's intention behind this, but i'm sure it wasn't as evil-meaning as i thought back then.
