We were only prescribed 5mg daily to start with, and never needed to go up from there. I would call them and ask to make sure. Also, when you dissolve it it breaks down into small little ball thingo's, the best dosing device we found was the big syringe that came with the nurofen 3+ months bottle, everything else left half of them still inside. We also had to use apple juice as DS would gag on it when we made it with water and it all just came back out again. Since you are giving EBM anyway, i would mix it with that to make sure she gets it all down

Good luck!
