Infants range from only a few weeks old to several months in this program! Babies will range anywhere from birth-7 months at the start of the semester. We recommend infants older than seven months register for mixed-age classes. The babies are non-mobile for the majority of the semester. If your baby is crawling before the start of the semester you may also want to consider a mixed-age class. Feel free to email us at eberry@jamminbaby.com to discuss.
