The list author says: "Baby Gear on this list are items that you can get a lot of mileage out of! Each item also has developmental benefits as discussed in my parenting on-line guide, stellarcaterpillar.com"
"A play pen is essential! Baby has her own space where she feels safe and secure to explore, nap, and play. Use this instead of a jumper or exersaucer to free your hands and encourage motor skill development."
"A bean bag chair gently conforms to her body as she is sleeping. When she is learning to stand up, she can hold onto it and pull herself up. It is also soft and gentle on her bones when she falls over, and it can not be tipped over."
"Babies and toddlers love the squeaky sound this toy makes. It is made of natural rubber with vegetable dyes, so it makes the "green" list. Plus, it is excellent for fine motor skill development of the fingers."
