Hi, my son has recently turned 4.
Around 1.5 months ago, I began to notice him making involuntary sounds. These include humming and whistling, he also has began with involuntary face scrunching and his tongue is constantly in and out of his mouth. He also seems to be reverting back to not using language to ask for things, rather pointing and making a whining sort of noise. I've also realised he is taking huge big loud breaths.
Any ideas? All appreciated. Thanks so much.
