I came to bed at 10pm and this is the third wake up of the night already. DS is 17 weeks old and is so much worse now than when we was a newborn. I thought we were doing badly when he was going three hours but he's managed to prove me completely wrong and I'm not at the stage of not being able to see properly and I am constantly cold and shaking because I am so tired. I've gone numb to my life too and regularly burst into tears. I need to get away but I can't even have a break, during the day the only time he doesn't scream is when he is on me. I can't keep doing this.
