I'm on motilium as well since DS was 9 weeks old. I can't stop taking it due to supply either. BM is advantageous for my son because he is at high risk of allergies and food intolerances...and in fact does have an allergy and a gene for a gluten intolerance. BM can help delay or possibly prevent the onset of celiac disease and keep that gene latent. Anyhow this may not be a factor for you but it is amazing the potential benefits of BM so for me that outweighed the shift to FF. I'm not sure how long I will take motilium but probably as long as I give my son BM, but I don't think it will be beyond 1 year so I feel comfortable using motilium inside 1 year. My GP has no problems prescribing it and I believe it is often recommended by LCs as well. Oh, the paediatrician has no problems with DS getting traces of it over the long term.
