What age do LO's typically wean off the soother?
DS (21 months today) uses his only at nap time/bed time and in the car (not sure why, but now he loves going in the car-car just so he can have his su-su), so I'm not totally anxious to get rid of it. But, I just saw something about how toddlers can regress, which includes going back to using a soother, and I was surprised that a soother at 21 months would be a regression - I was expecting around 2.5 to begin that fight, not already.
DD never used one, so I'm in unchartered land here. Thoughts?
