I just saw this study linked from WebMD. They found that kids who used pacifiers for 3 years or more were three times as likely to have speech impediments. Frequent finger sucking also causes an increased risk.

When did you wean from the pacifier? Our LO is 7 months and is only given a pacifier for naps and bedtime. I was thinking maybe 10 months, since I've read that their need to suck diminishes then? I'm not sure.
