Thanks everybody for your replies. Just writing the original post made me feel better and reading the replies forced me to think about what was really happening and why I was feeling there was a problem.

I have come to the conclusion that I have been listening to the "should" brigade a bit too much. Every time I'd mention that she likes to fall asleep breastfeeding, someone always says "you should not do that, it will cause problems later", they would then also say"she should be on a routine!". Well now that I think of it she does have a routine, her routine. Feed, play, Feed, Sleep

Morning - Settles quickly, one big nap first thing, generally happy, enjoys play time on the floor
Afternoon - starts to get cranky, harder to settle, likes to be held more, but not all the time.
Evening - feeds more frequently and really likes to be held

So I am going to stop stressing, tell the "should" brigade to mind their business, and go with the flow. From what I can see, mornings are the best times for me to get things done around the house, afternoons are good for either an afternoon nap with DD, or to go for a walk with her in a sling to get her to sleep and the walk will hopefully help with shrinking my butt. Evenings, I think, are to be enjoyed. I would much rather sit on the couch, feed my bubs (which makes her happy), watch House, talk to DH and have a cup of tea than stand in a dark room, jiggling the bassinet with a crying baby.

For the next couple of weeks I am not going to try anything new other than to make more of an effort to give DD a massage after her bath. I think once I am less stressed, she will less cranky, then I will start to slowly try some different calming/settling techniques as suggested above. I will also pick up Pinky's book and the Peace baby CDS.

Oh, I am going to get my breastfeeding checked tomorrow at a breastfeeding clinic, just to make sure her frequent feeding is not a result of poor attachment. I still get sore nipples every couple of days, so there might be an issue.

Once again thank you for your replies.
