Feeding baby: time for a change?

In my purse I have a prescription for a formula that will be suitable for my multiple food protein intolerant baby. It's called Neocate and to buy it without prescription it costs £30-40 per 400g tin. Not a lot of GP's will prescribe it due to the cost, and I was prepared to go into my GP with my guns blazing in order to get this prescription for my baby. As it turned out, no guns were needed. My GP wrote the prescription without batting an eyelid and told me how to order repeat prescriptions if this is successful. What a blessing!

So now I have the prescription and the daunting task of making the transition lies ahead. I wanted the formula because although we've seen improvements since I've gone dairy, wheat, egg, nut, fish, tomato, citrus fruit free, my baby is still unsettled in his sleep and still has silent reflux. His diet is so basic that it can't be a reaction to his diet, so it must be mine. My health has deteriorated too, and breast feeding is taxing on my energies. I could really do without this added drain on my health as well as the freedom to allow other people to care for my baby.
Now I've got the formula all my hesitations are surfacing. I will miss feeding him. It's been a wonderful bonding time for us both and I have enjoyed the closeness very much. I worry that it will distress my baby, but I plan on making the change gradually so as not to distress him too much. And then there's the apparently awful taste of the stuff. I'm not quite sure how I'm going tackle that one!

My dream is to have a happy and content baby that sleeps well (for his sake as well as my own). Maybe the fire of my hope that we'll get there isn't burning bright right now, but it is still there flickering, gaining strength as we jump each hurdle.
