If its reflux the best thing is to get it diagnosed and medicated ASAP, no stuffing around, silent reflux slowly damages. There is no need to see a paed, a general gp can prescribe zantax or losec. Infants friend won't help with reflux though.

DD2 started about 3 weeks, within 2 days she was vomiting up her own stomach acids, I rang my gp, she faxed a prescription to my local chemist that day and we started zantac (I've had previous experience with GORD with my niece so my gp trusted my judgement). Within a few days she was so much happier, it took another couple weeks to calm down much more. At 5 months we trialled a decrease in med's and found she was much better, by 6 months she was off the meds.

If your bub does have reflux its not the end of the world, its quite treatable, and while you may find they are still a little irritable and sensitive because it may not hurt as such but still be umcomfortable, they can still be very happy little darls. There are heaps of little things you can do to help, like raise the cot, have bub sleep upright as much as possible (a rocker or swing is great for this), carry bub with you in a sling. Change bubs nappy before a feed and turn them sideways to do so not lift their legs to their chest. Dummies help produce extra saliva to reduce stomach acids, as well as being soothing. Try to space feeds out to a minimum, say 3 hours, what can happen as is the stomach empties it starts to hurt, and to help this they want to feed as the milk is soothing temporarily, unfortunately it become a vicious cycle as each time the stomach fills and empty's it can cause discomfort.

If you are worried about your supply then do some extra pumping to increase it but generally reflux won't affect your supply as whatever is being taken will be replaced. Reflux will make bub fuss at the breast, unfortunately there is not much you can do about this except persevere (it will get better with time), but giving a small amount of mylanta before a feed can help. Formula can also make the reflux worse, as well as hindering supply, so try to avoid it.

Best wishes, I hope it gets sorted soon.
