Hi Blakes Mum
Again, I don't have any miraculous solutions for you, but just wanted to let you know that I have constantly struggled to get my LO to take a bottle. Most days he takes no where near the reccommended 20oz minimum, and has gone as long as 16 hours between feeds, I know how very stressful this is.
As long as your Dr has ruled out any physical problems, such as thrush, then I think you just have to carry on as you are, and hopefully he will revert back.
Sorry, I don't have the solution, just wanted to say that you are not alone!
Good Luck
Lou
