Swings: Many swings come with toys attached and/or an adjustable seat that allows you to place more hanging toys closer or further away from your baby . Some swings even have MPC players built in! Rockers:Check for models that allow you to move the toy bar higher, lower, farther out of reach (depending on how old your child is) as they grow so it will always be interesting to them. Also, look for ones where there are different speeds available. This way you won't run out of entertainment options anytime soon!
