We can attest, from personal experience, that every girl has one pair of jeans that makes her feel better about herself than the rest (thank you, jeggings).And the littlest of ladies is no exception.For her there is Love My Tush jeans. The soft, all-cotton pants are designed to look like old-fashioned dungarees — but without any of the awkward stiffness that accompanies heavy denim. Flexible enough for crawlers and easy to get on and off for potty trainers, each pair has an elastic waistband, back pockets, and the requisite contrast stitching.Choose from eleven patterns, including stars and the crowd-pleasing sparkle denim in sizes 6 months to 2T. Because it’s never too early to start teaching her the importance of being comfortable in her own jeans.Available online at babydreamscollection.com, $42-$48.HARMONIZEPECO Family ConcertWhat: Curtis students give the lowdown on violins, cellos, and other string instruments in the hour-long program (ages 5-12).
