Mads - I use formula for Danielle's breakfast. She's been a formula baby most of her life - I had a lot of trouble BF and she rejected the breast after getting a bottle. Tried EBM for ages but gradually I dried up. I wanted to BF her longer but that's the way the cookie crumbles. If you can you could use breastmilk or you could use just cooled boiled water and just add a little fruit just so it doesn't taste so cardboardy. I'm wondering if you could use soy milk? I'm not sure - maybe something we can investigate.
