TLDR: The 0-6 month size is much, much too small We ordered the 0-6 month size in white, and while we were very excited about the design and construction of the headband, when it arrived, it wouldn’t stretch to fit our 1-week old. We measured the band, and at its furthest stretch, it was 7” long, for a total of 14” around. Wondering, “Is our baby’s head just gigantic? How could our 1-week old be too big for a 6-month old’s headband?”, we did a quick search. (We’re new parents, so we’re in full swing crazy mode when it comes to making sure our kid is within ranges. My guess is, if you’re reading this, you might be too. Hi!) Turns out, this data is readily available on the CDC’s website! Lo and behold, the average head circumference for a two-week old female is 14.1”. “0-6 months” with a 14” headband might be a reach. Now, things run small sometimes, we get it. But in order to check on if we had just received a defective band, we called L’ovedbaby to check on their sizes. They didn’t seem to understand our problem, stating that they had never had complaints, which seems odd given, you know, geometry. We expected something more along the lines of “Oh, good to know, thanks. The next size up is x inches”, but didn’t really get that answer. All in all, the product was way too small and the L’ovedbaby customer service was poor. Returned.
