A friend once told my husband, “You don’t really have kids until you have kids. Plural.” At the time, with one sweet squishy infant who was a ton of work, I thought it was a really obnoxious thing to say. Now I get it. Somehow double the children seems to equal quadruple the work. Parents of 3+? R-E-S-P-E-C-T. If you’re thinking of doubling down, here’s some info that might help.
