I tend to feed on demand, although its becoming a routine because he normally wants fed every 3 hours, except at night, he goes down about 930-10 and that's him til about 2-3 then he back up between 5-6, so he falling into a routine himself, he is 5w 3d x
With my twins they were born at 32 weeks and when they came home from the nicu I feed them every two hours for the first few months. Until they gave me clues and then i feed on demand.
I always nursed on demand. Sometimes it's a matter of just wanting comfort when you're nursing them.
But I was told unless they're going too long between feedings to just let them let you know when they're hungry
I feed her on demand but if she sleeps more than 3 well more like 4 hours i will wake her.. cause when she wakes up after so long she is sooo hungry and swallows like shes never eaten before and it can give her colics. :s chugging like that. plus i dont like seeing her sleep somuch :c haha
Ive always just fed them on demand. They always got in a pretty decent routine on their own after a little while.
