Hi K.,
I was in the same boat that you are was very nervous about weaning my son this winter. However, I got very sick and since he was over 11 months old, the doc let me switch him to whole milk. I had pumped quite a bit of milk (about 40 bags), and gradually added whole milk to his bottle. The first night that he got half whole milk, he was really upset. However, the next day he was completely fine. Within a week, I was able to give him either whole milk or breast milk. I hope that this helps!
