My LO is 9 months old & I've gradually seen my milk decreasing the last few weeks. I'm still pumping 3 times a day during work for 15-30 minutes each time. I also have been eating a bowl of old fashioned oatmeal for breakfast & drinking plenty of water. I used to get at least 3 4oz bottles of milk & now I'm lucky if I get 2 3oz bottles. For example when I pumped this morning I got 2oz from my left breast & 1/2oz from my right. I'm concerned because I only have 2 work days left in my freezer & my LO eats 3 bottles while at the sitters on M,W,F. I'm thinking about supplementing since I'm no longer producing enough & I've been saying that once LO is 12 months, I was no longer going to be pumping & switching to whole milk.
What are my options with supplementing? Can the sitter mix breast milk & formula? what about whole milk? Could we slowly introduce whole milk so that LO will be ready for it @ 12 months?
