My 6.5m has hit some crazy sleep regression where he will only sleep for 45 mins at a time. I am at the end of my tether and struggling to cope. He wakes crying and shouting and the only thing that settles him is the breast. He used to sleep okay ish ( up twice a night) and can self settle but this seems to have totally gone out of the window. His naps are generally fine. He won't co sleep and doesn't use a dummy. Please someone tell me it gets better. Thank you
