Sometimes children really struggle to blend and I use these to help. Smooth blending is helpful for children who cannot put those sounds together. Try and make the sounds blend into each other even if the sound is a short sound. For example iiiiiiiit, aaaaat, iiiiiin. Try singing it to help. You won't always need to do this. It is often a eureka moment for some children when they eventually click.
