Baby Not Eating

The past few days have been such a struggle to get her to eat. Yesterday she had 24oz of formula and I feel like I forced an extra feeding in her and she only wanted about 19-20oz.

She typically has around 28oz a day.

Same thing is happening today. I’m trying to follow her lead. Today I tried giving an extra ounce but spaced her feeds out longer.

Should I call the doctor?

Is 19oz enough if that’s all she wants?

She is in the 90th percentile for height and weight so she isn’t tiny and should be having 28-30oz for her weight.

Edit: Baby is 12 weeks
