Hi Hun,
Aptamil is meant to be the closest to breast milk. Mia was combi fed with sma gold but the sma really didn't agree with her as it is known to be quite fatty and heavy. She is now and on the normal aptamil solely and is great on it. If u google sma gold u will see alot of mums with bad reports about it. It made Mia sick, constipated and gave her awful wind. Cow and gate is meant to be good and is similar to aptamil. its trial and error but I'd go with aptamil if I were u xxx
