Hi there, I flavoured the odd bottle with milkshake powder (one that has no milk protein in it), only on hv advice as abbi was drinking virtually nil. Its not recommended due to the sugar content and that it can make babies fat. Some people have used like some sort of essence in it, like vanilla essence, but again, I dont know if this is recommended. When she is 1 yr, you can have the flavoured neocate like my abbi has now. Hang in there, it does taste nasty but sometimes it just takes some getting used to x
