Having just gone through the potty training "experience" and debating with myself whether I should start early or late, there are a few things I learned. I don't think it's a bad idea to get the child used to the idea of sitting on the seat and sitting there without a diaper. However, if at any time, the child feels like he is being pressured to go and he isn't showing any signs of readiness (i.e. "holding it" for a period of time, wanting to be alone when he pees or poops, telling you he's going potty, etc.), then pressuring him will only delay the whole process. It has to be something he warms up to and makes his mind up to do. As long as she's just introducing your son to the potty and making it an enjoyable experience for him, I wouldn't be concerned yet. The moms I talked to when who started their kids at 7-9 months all said the same things to me. Their kids were not FULLY potty trained (staying dry 2 or more hours, going on their own, asking to go) until they were 2 to 2 1/2 years old, which is typical age if you start potty training when you see the signs of readiness. I chose to wait to for signs my daughter was ready only because the other way just seemed like more work with the same results. My daughter is 2 1/2 and we just finished potty training having started at age 2 when she started holding her pee for several hours. If your daycare provider wants to go through the work, though, I think it's ok as long as she isn't shaming your son if he doesn't go on the potty or if he goes in his diaper. Parents magazine did an "investigation" of sorts into the two forms of potty training - starting very early or waiting to start later. It was a very interesting and informative article. I may still have the article; if you are interested I can try to find it for you.
