Hun, I know it is very daunting thinking about the return to work. Both times I found that in reality it worked more easily than I expected.

At 10 1/2 months, your DS would be fine all day at CC without EBM if need be - certainly one bottle or cup would be enough, with solids and water. There is definitely no need to introduce formula at that age. You well might find that he feeds more often at night, but this doesn't mean he is not getting enough during the day. Part of it will be catching up on milk, but a lot of it is catching up on mummy!

All the best hun
