1 Aim to settle the baby for daytime naps and night-time sleep in a predictable way (eg, quiet play, move to the bedroom, wrap the baby, give the baby a brief cuddle, then settle in the cot while still awake). 2  Avoid excessive stimulation-noise, light, handling. 3  Excessive quiet should also be avoided.
The skeleton of the sponge is composed of tiny needle-like splinters called spicules, a mesh of protein called spongin, or a combination of both. Many sponges can only be identified by microscopic examination of the skeleton, which makes certain identification from photographs difficult.he collar cells have a sticky, funnel shaped collar and a hairlike whip, called a flagellum. The collar cells serve two purposes. First, they beat their flagella back and forth to force water through the sponge. The water brings in nutrients and oxygen, while it carries out waste and carbon dioxide.
sponges are the simplest form of multi cellular animals they are very diverse and come in a large variety of colours shapes and structural complexities they range in heights of 1 200cm and in diameters of 1 150cmthey have partially differentiated tissues and not true tissuessponges don t have internal organsthey don t have muscles a nervous system or a circulatory system their walls are lined with many small pores called ostia that allow water flow into the sponge the structure of a sponge is simpleone end is attached to a solid such as a rock while the other end called the osculum is open to the environment sponges are able to get microorganisms such as algae and bacteria for food through openingshe structure of a sponge is simple one end is attached to a solid such as a rock while the other end called the osculum is open to the environment sponges are able to get microorganisms such as algae and bacteria for food through openings
