Baby not finishing milk
First time mom here! Baby has habit of not finishing his milk (120ml), leaving 30-60ml and refusing to drink by crying and pushing bottle out with his tongue. He's turning 3 months in a few days, and this has happened for about a month. Weight was checked during his 2nd month jab, fortunately there was an increase in weight. Seeking help if this is normal or if there are ways I can make baby finish his milk. Thank you!
