christiana! Good to see you again!
I don't have any experience on early weaning, I'm afraid, but I did have a silent reflux baby. If I remember correctly it got significantly worse at 4-6 months.
My experience was:
cut out dairy in my diet at 2 months and gave peptac after feeds. Slight improvement in contentedness, but mainly in less congestion & spots in DD.
Black flecks in nappies at 3 months, disagnosed as 'old' blood, so prescribed ranitidine. Was very concerned about alcohol content of this medication, but it did significantly improve things for a time.
Began to lose the plot at 4 months with the teeth & BF, the arching, screaming, not settling EVER, explosive vinegary poos etc. and tried cutting out gluten from my diet at 5 months. We never looked back.
No-one ever suggested early weaning to me, but for some non-intolerant refluxers I can see that this makes sense - it's just a nutritious form of gaviscon, surely?
You have my sympathies - there is NOTHING more wearing and relentless and soul-destroying than trying to BF a silent refluxer. We really took a long time to recover after DD did.
