What shall I do? Help me mummies.

My 1 year 4 months old babygirl been rejecting her milk bottle. Only wants to drink her milk when spoon feed with biscuits or else she rejected the milk. Tried a few ways just to get her to drink milk as usual but failed. Shes on solid twice a day and snacks on biscuits and drink plain water happily. How can I get her to drink milk again? Is it due to her teething? Do I have to change formula milk? Please help me mummies please. Thank you. #pleasehelp #firstbaby #1stimemom #advicepls
