My sister had to go to a speech therapist when she was in school, so she thinks she's an expert on this subject.
But to be honest, I'm really clueless when it comes to this. I'm not sure if thinking she'll outgrow it/learn the proper way to say it eventually since she's only six is the right way to think or not. I guess I'm just asking for those who have btdt. I personally don't think she has a speech problem, per se, but like I said, I don't really feel educated on the topic, so maybe she does! The problem we have right now is not being able to pronounce the "th" sound. Instead she says the "f" sound. (Firty for Thirty.) While i'm on the subject, my four year replaces the "f' sound with the "sh" sound. Like instead of phone or fun, she says "shone and shun"
I feel like I should know if this is okay or not okay, so don't laugh at me lol. Any resources/links or advice would be greatly appreciate. Even if its just to tell my sister to mind her own business. Especially if its that.
