DS2 is almost 4 weeks and EBF, but things seem to be getting worse to the point where I just can't cope bad don't know what to do. 
He had a TT snipped a week ago but all the things I was promised would improve haven't and more issues seem to be coming up. He is gaining weight well but feeding is a fucking nightmare. I struggle to get him to latch on and he keeps falling asleep or falling off the latch, so it never feels like he's having a proper feed, just lots of snacks.
Current pattern is feed for 5 mins, he falls asleep (and no amount of tickling will wake him) so I put him down and within ten mins he's rooting again. He's probably managing two two hour sleeps in 24 hours -otherwise it's an hour or less each time.
I don't think he's getting enough hindmilk as his poos are green about once a day (rest of the pois are yellow, but at least one green one each day).
I don't wqbt to give up, mostly because I'm far too lazy to use formula. I EBF dc1 till 6 months but I don't remember it being this head after 4 weeks.
Help!
