Hi Alivia - your are not alone:-) my son is going to P1 too next year and having the same problem. We were quite lucky cause his teachers in his Childcare found out about his problem 2 years back. They wrote a letter of recommendation to KK Hospital. Started with his speech therapist early last year. It's a monthly check up with 1 hour 1to1 therapy.
You can try if you want to. My son have improve alot with his speech but writing a bit slower.
