It took me a awhile before I felt comfortable putting my daughter to sleep in her own bed, I was nervous about not being close to her all night and I researched crib mattresses to find one I thought she'd do well on. I liked the idea of foam because it's much more light weight, and liked the idea of soybean because it's hypoallergenic.
The best part to me is the fact that it's two stage... One side is for infants like her, and when she's older and we take the front of her crib off, we'll flip it over so she can lay on the softer side as a toddler.
