my baby is 9.5 months old and has been refusing milk. he is unable to sleep at night due to hunger, does thumb sucking but still refuses milk (night feed). He doesn't drink single drop of milk formula or breastfeed entire day. I have to force feed when he is asleep but now he is refusing that too. because of this there is a drop in his urine count too. He prefers solid but doesn't drink any liquid. what should I do?
