question: Hello doctor, I have a 2.5-month-old who I recently noticed developed a tongue tremor. I looked up online for the causes and found them as SMA. She has great motor control, we were not doing tummy time as often because she did not like it but have increased it and have seen a big improvement. My doctor believes it is benign tongue tremor, unfortunately, we had a telehealth appointment due to COVID so he was unable to see her but he told me not to worry and to keep an eye if things get worse. I am so scared it is SMA, what else should I be looking for?
