It is very common for it to take a couple of weeks for our newly starting preschoolers to get to know ourselves and the lessons and to settle in.
We will always persevere and suggest completing half a term to see how your little one gets on.
If for any reason they do not settle in to the classes we may suggest joining a baby & toddler class (with yourselves in the water) and will support you through this process and in finding an alterative suitable class wherever possible.
