very long time gap between fees

Older babies generally can go for longer without feeding. They can suck milk more efficiently as well so can drink more in a shorter time latching. If he doesn't seem hungry there's no need to force him, and actually being able to sleep longer at night without waking up for milk is a very good sign!

It’s ok. You can follow your baby’s hunger cues and don’t force feed him. He could be going through a leap/milk strike.
