Hi DS is 3.5 months, excl bf, and has horrid reflux and has been on Domperidone and Omeprazole for several weeks, his does increased recently. Hasn't helped that much (although he is less irritable, a couple hours a day rather than all day) so my Paed suggested the next step could be trying dairy free. I started about 10 days ago and not seen much difference yet. DS has an inflamation rash round his mouth which is still there and still refluxing quite severely after a feed/choking etc. I have been strict for about 10 days..no soya/milk proteins/eggs. How long should I go on with this before deciding it is not working? Thanks in advance.
