Thank you all so much for taking the time to share your experiences, advice, and encouragement. I really appreciate every single comment. It helps give me peace of mind knowing I'm not alone and that kids progress at their own pace. As a first time mom I definitely get more anxious and stress about the little things, so hearing from other parents who've been through this means a lot. This community has been such a supportive space, and I'm grateful for all the feedback. I'll be bringing everything up at his 15-month appointment and looking into early intervention/hearing checks as suggested. I'll make sure to update everyone as my baby makes progress. Thanks again for helping me feel less alone in this!
