weaning for formula? help!

brandy5879

i've been having trouble with DS and milk allergy was a likely culprit so i cut out the big dairy items, but knew i couldnt go to the point of checking labels for milk products, i'd make myself nuts. 

the last few days, he's been refusing to nurse and refusing breast milk in a bottle - he'll only take the soy formula we're supplementing with.

so after a week of being in denial that it wasnt working, i've decided i need to let it go and stop making us both miserable every feeding.  any advice on how to wean?   was thinking that i'd "pump to comfort" when i feel full and hopefully the milk supply will dwindle.  no idea how long it would take to go down though?  any thoughts or suggestions on how to do this?
