Not all reefs in the past were formed by corals: those in the Early Cambrian (542â513 Ma) resulted from calcareous algae and archaeocyathids (small animals with conical shape, probably related to sponges) and in the Late Cretaceous (100â66 Ma), when there also existed reefs formed by a group of bivalves called rudists; one of the valves formed the main conical structure and the other, much smaller valve acted as a cap.
You can engage your child on the floor once your little one can support his or her head with the Bumbo Floor Seat in the Blue style. The seat enables your child to sustain a sitting position on the floor, so you can read to, feed and play with him or her safely. Low-density foam in the contoured seat is comfortable for your little one, and a three-point harness keeps him or her safe. You will love the lightweight, easy-to-clean design.
Booster seats are the best way to keep your child safe in the car after he or she outgrows a harnessed child seat but is too small to correctly fit a vehicle's seat belt. The use of any booster seat will improve your child's safety, and likely his comfort as well.
