Worry or Don't Worry

Rebecca

My son is 15 months old. He doesn't say basically any words. Sometimes when he's upset he'll say what sounds like "mama" but that's about it. Some days he babbles a ton, and other days very little. Should I be super concerned? I'm giving myself horrible anxiety over this. I feel like my husband and I screwed up raising him already. Husband isn't concerned, that's the only reason we haven't taken him to the doctor about it yet. I also don't want to be that overly panicky parent. My son does seem to understand things when we talk to him. He does know how to get our attention as well if he wants us.
