My baby turned 7 weeks old. And her naps are increased to 4 hours sometimes 5 hours at night. She nurses for 5-8 mins sometimes it goes up-to 10-12 mins.

My doc said as long as she is gaining weight and has wet diapers then it’s fine to let her sleep for 4-5 hours. She was 5lbs 10 oz at the birth and now she is

10lbs3oz.

Now my question is would that decrease my milk supply since the number of feedings have reduced? Should I pump as well after every feed ? I am planning to nurse her for 6-9 months. Should I be concerned 4-5 hours of gap?
