While bouncers and swings are great ways to keep your baby happy and keep your hands free to get some work done, they don’t offer the variety of stimuli that baby play mats do. Baby activity mats offer more toys and also more visual stimulation, both above and below, than a swing, which might come with a couple of toys, if any. Play mats tend to be more interactive, developing your child’s important motor and hand-eye coordination skills. Tummy-time mats also offer an important strengthening component that swings and bouncers don’t.;Spending tummy time on a playmat relieves pressure on the baby’s head, helping to avoid bald spots or flat spots.;
