I feel like I might quite possibly burn out working full time and attending to a baby that is no longer sleeping through the night. Cohen has decided to start waking up several times a night and has done so pretty much since I returned to work (it started a couple of weeks beforehand so don't think they're connected). 14 weeks of uninterrupted sleep and now this. First week I thought it was a phase or growth spurt. Now it's been going on for about a month and it's getting worse. I feel a bit like I have a newborn again!
