You are most definitely overthinking it! But that’s ok. It’s understandable. We all can and have been guilty of over-thinking. For too long my very mild stutter held me back for years until I decided I had enough of being capped. What you should be focusing on right now is that your wife is comfortable and in good health. Being there and celebrating this occasion. It shouldn’t be a time or worry for you. It’ll be a while before your kid learns to talk. You’ll know yourself what signs to look and listen out for. If you have concern at this point then try and seek help/advice for what you guys can do as parents, and maybe therapy if needed. The earlier the better. But this is all hypothetical! Please do not worry about this. Take it as it comes. Are you going to worry from now until your kid starts to talk? That’s a heavy burden on top of everything else. I’ve spent too long of my life worrying about my mild stutter, and I was tired of being capped by it. I hate seeing this happen to others because I know what that feels like. On the off chance your kid does develop a stammer, it’s so important that you teach them to be open about it when necessary, that it’s not the be all or end all in life and accept it. I can speak in front of groups now because not only do I know they are just as nervous as me, but I try and project myself as someone who actually wants to speak. Totally different person to who I was 5 years ago. I wish I accepted mine years ago instead of ignoring it, but in hindsight I’m glad I am where I am now and not still stuck in a rut with it. Wishing you guys the best of luck! And congratulations on the baby! Get some celebrations in for you both.
