you aren't a bad mum, and you aren't a failure! You are doing a great job, I can only imagine how difficult it must get with two young kids. Is it possible your DS is coming up to a wonder week? could be why he is being so unsettled...do you have a sling that he might sleep in during the day? For quite a few months DD would only sleep in my arms during the day, just keep saying to yourself "this too shall pass". It's become my motto

Hope tomorrow is a better day for you all xx
