Hi, my daughter will be 9M on the 21st of July and she’s been steady drinking 8oz for about a month or two now every 3 hours except between the hours of 8p-9a when she is asleep. I just noticed recently in the past week that she’s not finishing her bottles anymore, leaving 1-2oz. Is this normal? Because of this she is struggling with sleeping through the night. She is also teething with 4 teeth coming in. Might that have something to do with it? Her 9M check up is on the 23rd of July.
