Sleep training - 5 weeks old

Jessica • FTM, May baby boy

My sons pediatrician recommended we cut out a feeding that he is not eating as much at, and the to get him to a 5-6 hour stretch of sleep. The one she recommended was the 3 am feed.

Typically he will wake us up to eat around 1230-1:30, then again at 3 since he’s used to his 2-3 hour meals.

No matter what we try to avoid feeding him, he will scream and cry. We will change him, rewrap him, and give him a paci. My husband has even tried rocking him. No matter what he will scream for an hour straight.

Any recommendations? Is it too soon to start cutting out this early?

Extra info: His weight is great, and we breastfeed.
