Add a bit of light and a few sound effects and watch the fun grow. Your baby can roll, sit and even step a bit when holding your fingers or clinging to the couch. It might be time this year to get a Christmas gift that will really get the party started. Babies love lights. Toys that blink or flash stimulate brain function and really hold your little one’s attention. You probably already have a variety of toys that come equipped with a light show. The addition of a few sounds and strains of music take the fun to another level.
