I’ve gone up a chest size with this - the ribbing pulls the chest in so much that I think if I don’t block the ribbing it will fit for a long time.

Provisional Cast-on with Spare Cable.
The first 8 rows set up the pattern after that it is plain sailing.

The first two photos are on my 4 year old, the 3rd photo is her wearing it when she was 3 years old, the last photo is on my 8 year old.

I use safety pins instead of row counters.
* Put a safety pin on the button band at
the same time as making a button hole.
* Put a safety pin on the stst next to a
cable crossing.
