My son is almost 12 weeks. We've been trying for over a month to gradually increase bottle feeds. When he does accept, he takes only about 2 oz! It's been an extremely slow process with little progress. I'm getting anxious and frustrated bc I have to return to work in a month and really wanted him to be completely bottle fed by then. When he's with me, he prefers breast and I have to say- makes sense to me! He is usually with just me all day.
