Background-I am working and pumping right now. Daycare has instructions to give Formula if the breastmilk runs out (has not happened yet.) We have provided them with milk-based formula. On occassion, no more than 1X per day, we give him formula.

Daycare will provide SOY Formula (Similac Isomil) if we want. I believe b/c of allergies they do soy. Would it be bad to allow them to give him soy? Eventually I would like to give him soy as a cost savings to us. I would love to not need to buy formula for Daycare once I wean.

Our supply of home formula is getting low and am wondering if I should buy soy and start the transition, but I don't know if I should wait until I am done breastfeeding.

Any thoughts?
