how many is can you find in:
q: why does ego need help sleeping? in guardians of the galaxy vol. 2, we learn that egos hostage traveling companion mantis is used to help ego sleep.
but why does he need help sleeping in the first place? and who or what did he use for living nyquil for millions of years before he acquired mantis?

a: presumably its supposed to be the case that he has some level of conscience regarding

 all the terrible things hes done (e.g. spawning offspring on a multitude of worlds, only then to murder them, and possibly his later essential slavery of mantis)

leading to serious insomnia.
how that timeline is supposed to interact with mantiss lifetime is another matter. but it could be that she could be very long lived, or that there have been others in the past. or its supposed to be that his insomnia is relatively recent.

edit:
i originally wrote presumably.   actually,  theres direct evidence. 
actual line:

 mantis:  he lies awake at night - thinking about his progeny.
