I have a 13 week old preemie who is up until recently was taking 3.5 ounces every 3-3.5 hours (formula). Within the past several weeks, she hasn't been taking nearly as much during the majority of her feedings. Sometimes only taking 2.5 ounces. Her schedule is 7, 10, 1, 4, 7:30, 10:30/11 and then a feeding at 3am.
She is not sleeping through the night and I'm not sure if that is because her adjusted age is still only 6 weeks old and she isn't ready yet.
I'm concerned she isn't getting enough. Am I doing something with the feedings that might be causing her to NOT sleep through the night? Should I change to a 4 hour schedule even if she isn't sleeping through the night to see if she will take more formula? Any help would be appreciated!!! Thank you!
