Mom SOS: Sleep Regression/Growth Spurt at 17-18 months?

After everything we’ve been through during the first 12 months, I thought the sleep Gods granted us mercy because our little one fell into a great, predictable sleep pattern that works for everyone… that until a few days ago.

The Small Fry is definitely going through some sort of phase at the moment where he stays up an hour or so later and then he cries and shrieks at bedtime.  He’s not really drooling much, so he can’t be actively cutting a tooth and I’m actually starting to think that possibly this is some kind of crazy growth spurt?  

Anyone dealt with sleep regression/growth spurt around 17-18 months of age? What can I expect? How long will this last? Is it common? Any strategies?
