How do you hide a pregnancy from family?

Back story I'm 23 and my husband and I are expecting our third! We have a 2 year old and a 1 year old. I just started going back to college for a new diploma. This baby is a big happy surprise. We would like to wait to tell family until we find out the gender. But that being said I usually start showing quickly especially this being my third. We have Thanksgiving, my sons birthday, my daughters birthday all before we will find out the gender. Do I wear baggy clothes? How do I do this?

(I'm currently insanely bloated but that happend with my first 2 in the beginning as well, no I'm not eating more mainly less)
