What can you suggest of a good formula milk???

It depends on individual baby. My girl has been taking Friso since birth till now 12 years old and my youngest also on Friso. You can try to request for sample for your child. https://shop.friso.com.sg/english/sampleproduct/sampleproduct/view?utm_source=Friso%20Singapore&utm_medium=Link&utm_campaign=Friso%20Singapore%20Sample%20Request%20Button&sampleproduct=MAC068
