Hi! Good for you teaching your baby! Keeping in mind developmental stages it is perfectly fine if baby is not interested in phonics at the moment. Generally it's not appreciated under age 3 as at this time kids' brains are right-brain dominant, and that half likes a more holistic approach.
I'm not sure what else you are doing apart from sensory, but this time is very good to learn word flashcards, bit's of intelligence and lots of exercise. If you need anything more, drop me a line!
