Neocate and losec are the luxury end of the scale which we seem to work our way up to after all else fails. Don't know but could you get a can of neocate now and switch onto that, while expressing at the usual milk times to keep your supply up then you would get a faster response. At the same time going on a DF diet so if things do improve and you go back to breast then there will be less diary there.
Or even use the medela supplemental feeding system with neocate as the supplement so you BF at the same time, while also reducing/ceasing dairy in your diet.
http://www.breastmates.co.nz/Medela_Specialty_Feeding_Devices.htmlAbout 10 days gives an indication of whether there is going to be an improvement or not but the older they are the longer it seems to take (my boy at 8 mths with solids in the mix took 5-6 wks - and it was a behavioural improvement more than anything). Now though if he accidently has diary the reaction is faster on a smaller amount.
I figure go for the top shelf and get things sorted and then move backwards to less premium products if you can - I swear my boy wouldn't be on such a high dosage of losec if I had got both my issues (milk and reflux) sorted earlier on - I just thought it was reflux only and couldn't understand why he was still so grumpy when he was on a good dose of meds. Now milk is sorted, pain is sorted, but reflux still occurs - and hope that is just a time thing now
