Annoying reactions to announcements

Vanessa
Anybody else receive annoying comments regarding you being pregnant? This is our second baby. Our first is almost 7 years old! We've both got professional careers, own a house, yes we are young both between 25-30. But for some reason we've had a few reactions that have been very painful. Sort of like a disappointed look, or you guys don't know what you're getting yourself into, oh you're too young. It's almost like you want to yell at the top of your lungs "shut up! And be happy for us" 
Sorry just venting and wondering if anybody else is going through this =\
