Someone tell me I'm not alone.
My lovely, chilled, happy, smiley baby has turned into the devil. He will not be put down, he will bit play on his mat, his sleep which was really good is now appalling, he throws tantrums for absolutely no reason and is inconsolable for ages.
I've read online this stage can last 35 days! I will be 100% grey and rocking in a corner by then.
