My mother-in-law and I made this dress (and a series of similar ones) for Rosa in early 2011, in a size 6-9 months. But now that Rosa is one-and-a-half, they still more or less fit (though they are a bit more mini than before!). I always love it when clothes fit a bit longer than a month or so, they make it seem that your baby doesn't grow as fast as she actually does! ;)
Look, Rosa already wore this dress when she was only six months old!
How time flies (and children change)...
