VQ excellent news. Fc is it a new trend (the 5hrs bit, not the wind/1.5hr/DH coughing/beer bit). Agree with pikz (& glad you're more relaxed too pikz).
chick fc too.
detective trust your gut. My DS has really sicky days, but I feel like I'm used to it as my DD did too AND with bfing, it could well be wind/something I ate etc. With DD she used to projectile vomit with mucous/a cold too, literally whole feeds. Nothing sinister at all. Both dc v happy pukers!! But if he's not gained weight & you just put your finger on something, then go with your instinct.
As for eating whilst bfing. YANBU!!! Was going to put everything glenda said. Seriously, when he has boobs, he gets an opinion. I had to sit and feed DS on Christmas night, because there was about 14 people around the table for supper & no room for me to bf. He was about 6wo & not long post TT so still taking a while to feed, so I was sat away from everyone else for the meal, unable to eat or drinking much as I couldn't always reach. DH did bring me some food to eat 1-handed but not all that I wanted. How is that selfish? And what are you meant to do whilst bfing anyway? Once they're latched on, that's it. You can hear them drinking, check them with a glance. I mean, its hardly requiring of your full attention surely? Perhaps we shouldn't read/MN/watch tv whilst doing it either, that's selfish too. Also, how do you sit in a cafe bfing when out & about w/out eating food/drinking? They went let you occupy a seat w/out making a purchase. I can get how drinking a scalding hot drink over baby might be selfish as its dangerous BUT food isn't that hot surely??!! And that wasn't the point he made...
