B.K.
I think that if you are worried, keep looking and find another doctor. From what you've said (between the speech thing and the foot thing), I think that you don't have a very caring doctor. Even with TennCare, I have been welcome to take my daughter to the doctor with even the most minor of problems and they have always treated me and my daughter seriously. She didn't even say more than her first word until after her second birthday, and anything that she did say would be like ... she'd say it for a few days, then stop. She was saying nothing, and making no progress. The doctor's told me that that happens a lot, and that she would grow out of it. They also said that most likely, she just wasn't talking because she didn't need to or didn't want to. I made it clear that I wanted her evaluated at the very least, and that was it, they made an appointment and gave her a referral to a therapist. It turned out, she didn't talk because she didn't need to. I was (still am) a SAHM, and so i was with her all day. I knew what she wanted, and I would typically get it before she needed to ask.
All I had to do was wait for her to ask for things like drinks or snacks. I even taught her a few signs (for the words more, eat, drink, daddy, etc.) and that helped a little because I would encourage her to use them, but when I used them with her, I would also talk. So she thought they went together, and after a while she would sign and talk. Once she got to talking, I stopped signing to her, and eventually it phased itself out, and now she talks so much that some days, I'm sorry i got her started! LOL ... But I wish you the best of luck, and if you want some more tips on how to get him talking, just message me, I'd love to hear from you!
