Sorry for the melodramatic post last night ladies. I'm okay now, thank you both. Just one of those nights where I have just Had Enough. Little man has not been well, as you know, but is on the mend now and is getting back to his old self. But he's learned that he can get himself into a sitting position from his front (where he sleeps) and so every time we tried to put him down to sleep he'd end up sitting up crying, and I know it's not his fault, but it took about 2 frustrating hours to get him off to sleep, him getting more and more OT. Then he woke up and (being a cruel, heartless mum that I am, or at least feel like now) I refused to feed him for more than an hour, offering him water instead :( He wasn't hungry - in fact, we managed to get him settled back to sleep in his cot a few times only for him to cough awake or sit up in his sleep. I felt awful and so at 2am I caved and fed him, and he had a nice feed and went peacefully into his cot until 4.45, then had another feed and, where that would normally be him awake for the day, I managed to get him back to sleep until 6.45am - our longest lay in in months.
In my head I want to be this perfect mum who doesn't mind feeding every 2 hours and meeting all my baby's needs day or night. But it's becoming clear that DH and I are going to have to start meeting our needs too (for sleep, for some kind of physical relationship, to start enjoying parenthood again) or trouble could potentially be on the horizon :(
Sorry for the essay. I think it's hitting home harder because we'd made real progress with his self settling to sleep over the past month and he rarely needed resettling before 9/10pm. It just seems to be one step forward and then two steps back.
This too shall pass. Hoping I don't have to wait 5 years though Button 
Queen That's so great, don't you just love it when that happens! :)
Joyful I'm so sorry your DD is poorly again. Sending get well vibes.
LWL Thank you for the get well vibes for BabyTickle - they're working I think. Seen some smiles this morning for the first time in ages :)
