A cot that adapts will take you safely through the different stages of babyhood and beyond. First position the base up high making it easy for you to reach your baby. When they can sit up, move the base down. Later, remove one of the sides so your child can get in and out without climbing over the bars. Experts advise against cuddly toys and loose covers in a cot. A well-ventilated mattress topped off with a washable mattress pad, fitted sheet and a baby sleeping bag is best.
