Not talking?

Ma

Anyone else’s baby not really talking yet? My 18-month old son babbles, but he doesn’t say any distinguishable words other than “mama” and “Gaga” (that’s his word for daddy). Our pediatrician recommended speech therapy if he’s not saying more by the end of May, but my sister doesn’t think he needs it. She has 4 kids and she took her first one to speech therapy, as recommended by her pediatrician, but she said it was stressful and didn’t really help so she decided not to do it with any of her other kids, even though it was recommended for all of them. None of them started talking until they were between 2-3 years, but they’re all on the honor roll at a private school now (except her youngest who is 2.5 and just started talking 3 months ago) and her oldest just got accepted to Stanford University.

Speech therapy sounds stressful, but obviously we’ll do it if it’s the best thing for my son. Just looking for other opinions and experience here. Has anyone else taken their babies to speech therapy? Did it help?
