Soon-To-Be parents often spend several months choosing the perfect nursery furniture and decorations, and then purchase a crib mattress as an afterthought. Mattresses may not be as exciting to buy, but it is one of the most important purchases for your child. A good quality crib mattress will support your babies growing spine and bones for the next 2-5 years. An infant will grow 1/3 of their adult height in just the first year! Plus your infant will spend up to 70% of his or her day on the crib mattress and your toddler up to 50% of his or her day. That is a lot hours spent growing and developing on a mattress!
