Babies in this age group are learning how to sit and stand on land and thus in the water they prefer to be in a more upright position. They may resist to be on their backs thus lots of encouragement is needed for them to float on their backs. When supported, they will use their arms and legs to move through the water. Towards the later part of this stage, the infants may be able to anticipate some sequences and may begin to learn simple cues in order to prepare for submersion. These experiences should be positive for them and only when they are ready should brief periods of submersion be initiated.
