Bed early to be alone/comfortable

Anyone else go to bed really early just to get some alone time and get comfortable? My youngest is 3 and goes to bed at 8pm. I usually lately am not far behind him. I just want to lay on my phone and enjoy my babies evening kicks and rolls and just relax by myself before falling asleep. My fiancé and one of my older 3 (19, 17 and 12) are usually down stairs watching tv till 10/11pm. Well not 12 yr old but older 2. But I just want to chill on my own for a bit, so I go to bed really early. Anyone else go bed early just to relax? I’m 26+3 btw
