We have just had a second disturbed night, which is very unusual for my little guy. He is preverbal, 2 years old, and is waking up crying at night. I change his nappy, give him a cuddle, soothe him off again, but last night... Nope. Not happening. I tried everything I could think of. His teeth are mostly through, so it could be teething still... but are night terrors a thing, and if so, at what age? How will I know? What can I do?!
