My son just recently turned one and he does not like milk I still breastfeed but I got to get him to drink milk and it doesn't help he's been sick recently so he's just really wanting to nurse and not really eat or drink anything. Is there another safe substitute for milk that I couod give him .He also still gets formula here and there only when I go to work . He usually a good eater except for now because he's still getting over a stomach bug that he had.
