@Fridgetapas they will learn both the sound and the name of the letter at the same time e.g this is the letter a (ay) it makes an ‘a’
Incorrect. They will be taught the grapheme-phoneme correspondence and be secure with that long before the letter names are introduced. Letter names come into play when more complex phonemes and spelling rules are taught and require distinguishing between the different ways to spell the same sound e.g. ee, ea, e-e, e, ie, y...et al, etc etc etc. In England, letter names are often held off until Summer term of Year 1 (age 6) and reinforced in Year 2.
I would only look on Little Wandle if that is the actual scheme at the school where the OPs children will attend. All synthetic phonic schemes have their nuances in teaching. Best to avoid confusion for all.
Unless you're home schooling, please leave phonics teaching to the school, and ask the teacher how you can support your child appropriately, at that time.
Before school, if you must dabble with phonics, support your child to hear the sounds in the environment instead. E.g. Go on a listening walk and talk about what you hear. Tune in. Read 'Going on a Bear Hunt's and talk about the sounds the grass/mud/forest/snowstorm makes. Listen for similar but different sounds, like bird noises. This is the most often forgotten and overlooked first step in teaching phonics.
Alternatively just let them enjoy being little kids.
