When my partner and I first became parents, we exclaimed over everything (and I mean everything). Our daughter's every move and sound practically made us jump up and down, either with excitement or fear. 18 months in, we no longer exclaim outwardly, but there are times I can read my parenting partner's mind and know exactly what he's thinking. Early morning wake-ups with a hungry child who's ready to start the day or the eighteenth time she's asked for blueberries in the last hour, I have a pretty good idea exactly what he's thinking without him saying a word.
Though the initial novelty of having a baby has worn off, and we often communicate more with grunts about our daughter's ability to clear the highchair tray with a single, infuriating swipe, there are also many things that I know make my husband light up. I can see on his face how happy it makes him when she runs through the house looking for him and shouting his name, or the images of future basketball games he gets when he sees her throw a ball. And thankfully, by now we don't have to talk about those moments every time, because I know what's running through his mind without him making a peep.
One of the benefits of being able to read your parenting-partner's mind is that it's instantly easy to figure out how to give them little breaks here and there. I know my husband hates changing stinky diapers, so before he has a chance to complain about it I usually take them on. Likewise, he knows how I feel about getting our daughter out of the bath (I always end up getting wet and it's always the worst) and takes on some of that burden from me. At the very least, being able to read your parenting partner's mind keeps the complaining to a minimum, relegating most of your responses to rolled eyes or a smile.
