Baby is 6 weeks old and nursing used to go great until about a week ago. She latches on and eats pretty good for about 3-5 minutes and then begins to scream and then pop on and off for the rest of the feeding while being very fussy. When I let down she sucks and gulps a lot but she doesnt choke or anything like that. I took her to the ped today because this has really upset me (and her) and I have felt like a failure and so I wanted to make sure nothing was phsically wrong with her. The ped said that physically she was fine-gaining weight (was 6lb 5 oz at birth and today was 8lb 12oz) and that maybe it was reflux. She also mentioned OALD/oversupply and I told her I didnt think that was the issue because she doesnt start screaming until after the initial sucking/gulping phase. She told me to try feeding her more upright and if that doesnt seem to help over the next few days to start giving her the zantac. Im so confused because reading a lot of these posts it sounds like maybe it is OALD but then maybe its reflux. Im nervous about trying the block feedings to decrease my supply if thats not really the problem and then losing my milk supply. Im so confused-I dont know what to do because i dont want to do the wrong thing because i want to breastfeed so bad--please please help!!!!!!
