Hi there. I'm new to mumsnet so thought I would just say hello. I'm a single mum to a dd aged 7 months. I'm doing a PhD and was just wondering if there's anyone else out there in a similar situation. I go through weeks of coping pretty well and then others (like this week when dd's dad is visiting) when I drop a ball and my work falls by the wayside. Have been up and down with dd last three nights due to teething so pretty exhausted and now that she's started sleeping ok, I'm stressed out by being behind with work so now can't sleep myself. Any success stories out there to make me think it's all possible?
