My 7 month old is ready to have follow on milk.

The milk is used for babies 6 months onwards and contains extra nutrients to support the weaning diet that my son now has ( with him eating more food than before )

My question is this ...

Can I go from his first milk and suddenly change it to this milk or do I have to wean him into it???
