My son is 11 months old (almost 1) and the last two weeks has been a completely different child!
He's usually so happy and playful and independent but now it's like he has had a personality switch!
He won't let me put him down without screaming the house down, he doesn't like to be held unless I'm standing. He is refusing naps, food and isn't sleeping well during the night.
He screams murder if I put him in his buggy or car seat.
It's getting really down because I want him to be happy 
(I do not agree with cry it out or controlled crying btw!)
Thanks in advance for any help!
