For younger babies use a lying entry: the baby lies on a baby mat on poolside. The adult sits on the side and enters close to the baby without splashing. The adult then lifts the baby into the water under the armpits and with the head supported if needed.
For those who are able to sit, a sitting entry may be used: the learner sits on the side unsupported but under close supervision and is drawn in toward the adult in the water. The adult then returns the learner to poolside. The accompanying adult must show they are able to safely access the water whilst fully supporting the learner.
