Hugs, we had endless bf issues with T. Forceful LD, imbalance etc. I think his reflux/intolerances also contributed to problems with feeding as he developed a bit of an aversion to feeding and only ate just enough YK?
I had some success with block feeding but I couldn't get the balance right. I had too much then too little, and things never came right.
I would defiantly try 4 hrly block feeding but may eh old off on any more for now. Try expressing a little onto a towel when your LD comes too.
Hugs - how is the reflux? Intolerances?
