OK flowers - first relax. Its very early days, this won't last, things will probably get better by themselves.
Breastfeeding is mad, completely mad. Bear that in mind - it WILL get better.
If baby seems to need to feed constantly then go with it, it WON'T last. If you think its just comfort, then so what...it won't last.
Don't try to do anything - at all, expect to be stuck on the sofa for the next month. Think of it as Mother Natures way of helping you to get over the birth. It won't last and you'll reap the rewards later (easier to get out and about, baby less likely to be ill etc etc).
I'm not convinced its wind, it could be but not necessarily.
My advice - the technical bit - is to try to make sure that baby gets a full feed each time. You won't know for sure but here's a way to give it a shot.
Feed baby from one breast, she'll probably drift off at some point, lift her up over your shoulder and wind her. Rub hand firmly in a circular motion on her back. This should (a) help wind her if she needs it and (b) stir her awake again if she isn't really that tired.
Then, put her back on the SAME breast and see if she carries on. If she doesn't, put her to second breast and again, if she drifts off, wind her and offer her second breast again. If she drifts off again then she probably is ready for sleep.
The reason I suggest offering her the same side again each time if that if you switch too soon then she could be getting too much foremilk. This could mean she'll get a tummy ache and also not enough of the good stuff to help her sleep very well.
Don't look at the clock to tell you if she's had enough, look at your baby. Don't keep track of how much she has fed and for how long. Don't worry about at what point foremilk becomes hindmilk. It doesn't matter, go with it, it won't last (did I already mention that ).
Try to give FULL feeds each time, even in the middle of the night when its tempting just to top her up and go back to sleep. You're both more likely to sleep longer if she gets a good feed.
Another thing to think about is to put her to bed earlier. I know its hard, you want her with you all the time. She probably goes to bed with you, right? She may be getting overtirred so try to bath her and help her unwind before she gets out of hand. If she starts to howl at 7.30 then start to bath her at 6-6.30 and try to have her fed by 7. I'm not saying she won't be waking up yelling by 8-9 but you at least will hopefully get a bit of a break.
Something to look forward too...at about 4-6 wks when you think you've got the hang of b/feeding. Think about expressing milk. You can either do a little each day (alot if you are lucky) and then each night, or save it up for the once a week, you could give baby a bottle at 10-10.30ish. Ideally someone else should give the bottle because she's more likely to take it but it also means you can have an early night.
DON'T WORRY - IT WILL GET BETTER !
