Getting 5 month old onto formular

Wish I knew what to say.

Blessedtobe suggested a drop or 2 of vanilla essence to make it more tasty. Otherwise try different formulas.
K takes Nan and Lactogen but refused S26 - I have a full tin at home if you want to come get it?

Hey moms, Scarlett is 5 and half months, ive been back at work since the 10th Jan, shes drinking my expressed milk from the bottle but i would really like to get her onto formular now.

Ive tried Nan but she she takes one sip and pushes it out of her mouth. I have to go home around lunch time everyday to feed her.

Any suggestions, shes with my mother in law during the day and she keeps trying but no luck
