What the baby wants, the baby gets - most of the time. As you know, when babies are displeased, they make it known with an ear-splitting level of noise, which makes it urgent to set things right. However, while babies do not always enjoy tummy time, it's not optional: in early infancy, time spent on their bellies is necessary for babies to develop their neck and trunk muscles in preparation for crawling. In order to cajole your baby into spending some time on his tummy, you're going to have to keep him entertained, and the Fill N Fun Water Play Mat from International Playthings will do the trick. A clear inflatable window at the edge of this activity play mat (which you will need to fill with warm water) is full of five colorful floating fish. Your baby will be fascinated by the colors, the shapes, and the novel feeling of the water, and will happily submit to tummy time for the treat of exploring the fishies. The International Playthings Fill N Fun Water Play Mat is easy to empty out and fold up for fun on the go; made from phthalate-free vinyl. Suitable for newborns and up.
