Other baby app isn’t help... I have a 3 month old. She eats 6-6 1/2 ounces 4-5 times a day. Yesterday and today she has only ate 3 times. I’m fairly worried.
My son would do that sometimes during growth spurts. He would eat close to 40 ounces a day and some days it was a struggle to get him to eat 20 ounces. I'd call your pediatrician and see what they would recommend
