Flu shot....

Alex
I'm 36 wks... Should I get my flu shot ASAP? And what about my husband and 3yr old? All need flu shots? Lastly my mom will be staying w/us for about an month after baby is born... Should she have one? And a Tdap? She hasn't had one but myself, husband & son all have. 
And where do u get the flu shot? 
Thoughts?!
