Thanks for your help! We tried mixing 4 oz EBM and 2 oz formula, but he wouldn't take that either! I hate wasting what little stored EBM we have left!
I'm new on here, but it seems like most of the posts are for introducing a bottle and he takes the bottle fine....as long as it has EBM in it! I haven't seen many posts on introducing formula at a later age. Now I'm regretting not introducing it earlier...
