Hello doctor.. My daughter completed 10 months this 6th.. She used to drink (70 to 90 ml per feed) her formula 4 times a day. I give her formula when she naps in day/sleeps at night. Suddenly she stopped drinking all of a sudden totally. She loved water.. Even refuses that now. Not any new teething... Herurine amount is lesser than normal...
Hi...unless she is deny Chat Doctor.  Activity is more important than anything else. I suggest you observe for another 2 days and if the urine output is gradually coming down or if she is dull and lethargic, I suggest you take her to the pediatrician. Regards -
