I could really use some reassurance

Faith

My son just turned 9 months a few days ago and he is still not yet babbling. He just says “ ahhh” or “wahh”, blows raspberries and that’s it. I make the M and B sounds to him multiple times a day and nothing is working. He does crawl and pull up on things. He was born at 36 weeks but at our 9 month appointment the pediatrician didn’t think that was something causing this. She wants us to have his hearing tested again since he hasn’t had it since birth. To me he seems to hear fine. If I were to make a sound behind him he would turn around. I’m just so worried 😭 we have also had a ton of issues with food. He hates eating and has little interest in it. Not sure if anything could be related to that since they are both oral muscles used. Just feeling really anxious and defeated. Any similar experiences?
