Jen had a good suggestion of trying to get someone to meet with him at your house. If you're willing I would try and locate the number to the local Parents as Teachers and have her sign him up. Of course, you'll have to just hope that she actually does it. You could offer i suppose, but I 'm not sure if that will work. Anyway, maybe they could meet wtih the child at your house, although that's not ideal, maybe at least for one of the initial times so you could ask questions and voice your concerns too. As I type it out, it seems more unrealistic than it did in my head, but maybe it's worth a shot. I would just ask some follow up questions about whether or not she's made an appointment for him at the speech path., etc. I would even ask your own pediatrician the next time you're there for some ideas on how to help, etc. In the end, I think maybe you just need to tell her that you're going to start him on some finger foods. If she throws a bit fit, then of course you can't do it, she's the mom, but I bet if you press it just a bit, she'll probably cave and let you do it. Maybe if you start offering it to him he'll start to get it or at least be interested. I wish I had better advice, this sounds like a tricky situation! Good luck and I'd be interested to know how it turns out!
