Mummy neeeeds some sleep 😴

First time mom here, I looovvee my baby! Best thing in the world everrrr!!! when my son was 3-5months he would sleep a whole eight hours giving mommy & daddy some time to rest up! But since he clocked 6 months ( he’s 7 now) he wakes up every 4hrs for a feeding.. am having to wake up twice at night leaving this momma exhausted, he takes 2 trained naps during the day ( mid morning & late afternoon)my question is - is there any advice you mommas can give me? Should I eliminate late afternoon nap so he can sleep longer?
