Attempting to securely prop your baby into a sitting position is doomed to failure, but it's important for babies to practice sitting up. It helps them develop muscle control and lets them look around and participate in whatever's going on. The Bumbo Seat is a deep, comfy seat which holds a baby upright and allows him or her to practice sitting without the danger of falling over. It's safe, hygienic, and handy! $39.95 USD.
