It will pass hun. I had my darling boy waking up every 1-3 hours every night for 5 months between 4 mths old and 9mths old. He now sleeps every night from 7-7 and only wakes if he is hot or sick, and he sleeps for 3 hours during the day every day, at nearly 2. At the time though I was ready to run away and join the circus. I was SO exhausted so I totally feel for you. If I get less than 4 hours in a row then I feel horrific. Can you go to bed early and get your DP to get up so you can get a bit of a longer stretch?
