awww Maranui I'm sure it's just a rough couple of days... he will get better soon .
William also isn't too fond of the taste of the dummy and spits it alot. When I know he's not hungry and just wants to comfort suck i usually hold my finger on it for about 20seconds so he can't do the repeated spit and rock him a bit or rub his tummy to calm him and it seems to work. It doesn't work when he's really really unsettled, so out comes boob until he pretty much goes to sleep.
As for BF yes i definately break it off when its hurting, especially now that I know what it feels like for it not to hurt. Still hurts a bit when he first starts to suck though.
As for the tingling at random times - yep i get that. Was coming home from the shops and I had it in both boobs at once lol i actually had to hold them cuz it was kind of painful. I was wondering if the sensation ever goes away... it seems that it probably wont.
I won the Pricillia Dunstun DVD on ebay for cheapish yay... although i'm getting good (i think) hearing the different cries without watching it. yay for me. It's really helpful actually. Especially the burp one
