Once your baby is born you quickly learn what size clothing will fit him or her correctly. LTD was a fairly average sized baby, so he was able to wear age appropriate attire from day one. He moved from Newborn to 0-3 months and now he is rocking 3-6 months gear. Of course nothing is ever easy because it feels like all the companies that make baby clothes got together and held a secret meeting the outcome of which was an agreement that all their clothes actually be different sizes but all their labels would say the same size. If they didn’t have a meeting how does one explain the size differences between clothes that claim to be the same? For instance, we bought a shirt the other day that says it is for the 3-6 month age group, but it was the same size as the 9 month shirt I bought way early cause it had Batman on it. I understand that every clothing manufacture does things their own way and we don’t want to live in a soul crushing 1984-like world where all things are the same, but I think we can all agree that all size 6 months should be universally alike. I have enough on my plate without having to measure baby clothes.
