HI- I have 5 month old twins who were exclusively breastfeed until last week. My husband had been giving one 8 oz bottle each evening to them of expressed milk. Last week, I began giving them soy formula in that bottle due to not having time to pump 16 extra ounces a day (also have a 3 year old in the house!). It has been going fine-no problems. They have received a bottle of some milk, some formula-also no problems. My husband loves this special bonding time with his babies and it allows me a bit of freedom. Good luck!
