If your baby sleeps 10 hours or used to.....did that change to them sleeping more overnight? When?

My son only ever sleeps 10 (mayyyybe on occasion 11) hours overnight. When he goes without a feeding at night it's 10 hours on the button. I'm wondering (hoping) if this will ever change. 7 p.m. bedtime works, but 5 a.m. wakes suck. He takes about 3 hours worth of naps during the day. He's just never slept more than 13-14 hours in a 24 hour period. He's almost 8 mos.
