My two boys, being close in age, have a lot of clothes that look interchangeable, with only a slight difference in size. This means that they regularly wear each others’ clothes and my older boy will come out in high-water pants while my younger son has pants that drop around his ankles because he’s not wide enough to hold them up. The only time this becomes an issue is when the mix up happens with their underpants. It’s not a big deal for my younger son, but when my five-year-old comes out in 3T briefs, I start to worry. Now that they mostly dress themselves, I don’t discover anything until bedtime, or when my older boy’s eyes start bulging out of his head. That’s when I do a quick clothing label check and then suggest that he and I go back to the dresser and maybe pick something that would help him breathe better.
