I just wanted to post to say that perma feeding for a newborn is normal!! It is very normal for bf babies to appear never satisfied. If you can just keep offering boob. Set yourself up for a couple of days if just resting in bed and perma feeding your baby. Get some DVDs and comfy trackies.
I struggled with supply for months with DD. Only very high doses of motilium had any affect for me. I hated expressing because it was like I ALWAYS had my boobs out but I was always really grateful for the bottle of EBM I could give to DD in teh evening when I was just OVER a baby being attached to me 24/7.
