Sorry to hear of everyones woes 
I do come on here and read our thread a couple of times a day, but I often then don't get time to post. You know the story, crying baby, whinging toddler ............... 
Frakk - pulling off/woodpeckering. Sounds like one of three things to me:
- overtired and comfort sucks to go to sleep
- wind / discomfort of some kind
- wants to comfort suck, but instead of butterflying with his tongue for comfort he's sucking and getting milk - which he doesn't want.
Of course it may not be any of the above, but they would be my best guesses!
I was a month old yesterday and we had our last MW appt. He was is now a few oz over his birthweight, so he's 11lb 6oz. I cried when the MW left, I felt so emotional that that part of the pregnancy/birth/newborn phase was over 
Whoever mentioned weighing. DS has been weighed twice since birth. I won't be going to the HV clinics, just every few months I'll do a rough weight at home. In your heart of hearts you can tell if they are doing ok. Growing out of clothes, wet and poo nappies, defined awake and asleep times. Constant weighing just seems to make me fret rather than reassure me, so I choose not to weigh very often. But of course, some people find it a source of comfort ........ horses for courses and all that.
Now off to look at the sling site with credit card in hand ............
