I am trying to introduce formula milk to my 9 month old who has been exclusively breastfed but he's not having it at all. Tried Aptamil, SMA, Cow & Gate, HIpp but no luck at all.
He has solids 3 times a day but he still needs milk, please any advice on how to make this transition to formula?; I am due to return to work in a few weeks and I don't have enough breastmilk to express for him in my absence...
