Feel bad..

I feel like a bad mother to my daughter. She's nearing 15 months old and hasn't said 1 word yet. Her doctor said that if she isn't saying at least a couple of words before her 15 month appointment, we're gonna have to put her through speech therapy. I've tried reading books to her but she either just slaps the book away or just doesn't pay attention at all. She doesnt want to learn to walk either... I take her outside with her zebra walker and put her shoes on her to let her get used to walking but she has little interest in learning. Idk I'm just ranting here hoping I'm not alone in this. Sorry for the long post and thanks to whoever read this
