Awwww, it sounds like normal 'toddlerhood' to me, not that it makes it any easier for you hon!

I hope this passes soon, such a big change in behaviour is often a developmental leap as the other lovely ladies mentioned, so hang in there

Sounds like you are doing a great job, just keep being consistant and distract, distract, distract!

Heaven - you have inspired me to get Pinky McKays Toddler book in advance to prepare also , I really enjoyed her "sleeping like a baby"
