When my ds was 3 weeks old he started projectile vomiting. It got worse and worse until it was after every feed. He was also "colicky" and would have episodes of SCREAMING with back arching and rigid tummy. He would fight the breast, gag, etc. Pedi had him sent at 4 weeks for upper GI series which supposedly was negative for reflux as well as for pyloric stenosis. I read up on the net and I became convinced it WAS reflux because of the symptoms. I started feeding him smaller, frequent feedings, agressively burping him every FIVE minutes (ack!) and sleeping him tummy down at 30 degree elevation. This helped the puking somewhat altho he still would it was less forceful and less frequent, but did not help the pain or the fighting the boob. It was literally a struggle to get him latched on and kept on. He also had a really crappy latch and never latched well from the begining and I had late milk supply (c-section, didn't latch first time until almost 18 hours old, had bottles against my will, and milk came in day 5).
Anyway, I had gone to an online community looking for support for my bleeding cracked nipples and somebody, bless their hearts, read more into my post and his history and suspected not only overactive letdown, but oversupply as well. (Oversupply is often found in conjunctino with overactive letdown. ANd the oversupply/too much milk/foremilk-hindmilk imbalance can lead to many of the PAINFUL symptoms of reflux like the arching back and the belly pain, from too much lactose in the foremilk which makes them bloated and gassy.) It was literally a godsend, because I swear it saved my nursing relationship with my son. At about 6 weeks old I got this information, and started following the suggestions to help slow down my milk ejection, help baby deal with it better, and also to slow my milk PRODUCTIOn and help baby get less foremilk and more hindmilk. Within one week it changed EVERYTHIGN. No more, or very minimal fighting the breast. His pain went away almost overnight. The puking tapered down and eventually went away. Baby slept longer, seemed more satisfied, didn't need to nurse every 45 minutes. ANd his latch improved (partially because I think that he wasn't latching well because is he GOT a good latch he was choking/drowning on milk - why bother sucking properly if you can just sit there with your mouth open, lick the nipple, and get sprayed with milk ?)
Anyway, I will post you links to some infomration about it so you can read it and see how EASILY the two can be confused. For me, it is the opposite of your position, I would have done ANYTHIGN to avoid the weeks of agony thinking my baby had to have surgery or had something like that, being unable to help him screaming his head off in pain, having to FIGHT him to get him to take the boob thinking something was wrong with me, and have that tenseness everytime it was time to feed him. I DREADED nursing him. I had never heard of it, and my pedi never had either. Bad bf advice had me doing things like switching boobs every 20 minutes that was just makign things WORSE not better.
Now I just had my 2nd baby, and altho it is not as bad as with my first, I have again developed oversupply (altho not having the issue with the overactive letdown) and am having to manipulate my nursing schedule to the point of nursing one boob only for FOUR hours and she is only one month old and altho her gassiness and pain and nasty poop has improved she is still intermittenly greenish (from night feeds where I am so engorged and too lazy to pump - sometimes I will pump off an ounce or two of the foremilk when I know i Have like 80 ounces in my boob ROFLMAO) but she is STILL puking but only once a day vs. 4-5 times. It is taking a little longer because she has an AWESOME latch and when she comfort sucks she is getting still so much milk she just fills up so quickly. blah-blah-blah. Check out the links and they should give you lots of infomration on how the two issues can be confused so easily.
And lastly, my dd was born via VBAC ! I posted her story on the VBAC board, you can read it there if you'd like !http://www.lalecheleague.org/llleade...Jan98p123.htmlhttp://www.lalecheleague.org/NB/NBMarApr98p43.htmlhttp://www.lalecheleague.org/llleade...pOct95p71.htmlhttp://breastfeeding.hypermart.net/toomuchmilk.html
Also if you just go to the LLL site and under search type "finish the first breast" you will get a really great article but my link is not working. ALso type oversupply or overactive letdown and you will get alot more articles. I hope this answers your questinos (some of them) Good luck !
