Trouble eating

My 2 month old is eating in increments. She’s not sick or anything. She usually eats 3 1/2- 4oz per feed. Now she’s eating maybe 2 oz at a time, then another 2 a few hours later. Anybody else experience this? Any advice to get her to eat all at once like she used to? Update: My husband and I went to Walmart and got the Dr Browns anti colic bottles to eliminate gas and it worked. We’ll continue to see if it works throughout the night. If not, we’ll definitely get some gas drops or something.
